The Components of Hard Disk Drive 2



Recording Media


No matter which substrate is used, the platters are covered with a thin layer of a magnetically retentive substance, called the medium, on which magnetic information is stored. Three popular types of magnetic media are used on hard disk platters:

  • Oxide media

  • Thin-film media

  • AFC (antiferromagnetically coupled) media


Oxide Media

The oxide medium is made of various compounds, containing iron oxide as the active ingredient. The magnetic layer is created on the disk by coating the aluminum platter with a syrup containing iron-oxide particles. This syrup is spread across the disk by spinning the platters at a high speed; centrifugal force causes the material to flow from the center of the platter to the outside, creating an even coating of the material on the platter. The surface is then cured and polished. Finally, a layer of material that protects and lubricates the surface is added and burnished smooth. The oxide coating is normally about 30 millionths of an inch thick. If you could peer into a drive with oxide-coated platters, you would see that the platters are brownish or amber.

As drive density increases, the magnetic medium needs to be thinner and more perfectly formed. The capabilities of oxide coatings have been exceeded by most higher-capacity drives. Because the oxide medium is very soft, disks that use it are subject to head-crash damage if the drive is jolted during operation. Most older drives, especially those sold as low-end models, use oxide media on the drive platters. Oxide media, which have been used since 1955, remained popular because of their relatively low cost and ease of application. Today, however, very few drives use oxide media.
Thin-Film Media

The thin-film medium is thinner, harder, and more perfectly formed than the oxide medium. Thin film was developed as a high-performance medium that enabled a new generation of drives to have lower head-floating heights, which in turn made increases in drive density possible. Originally, thin-film media were used only in higher-capacity or higher-quality drive systems, but today, virtually all drives use thin-film media.

The thin-film medium is aptly named. The coating is much thinner than can be achieved by the oxide-coating method. Thin-film media are also known as plated or sputtered media because of the various processes used to deposit the thin film on the platters.

Thin-film-plated media are manufactured by depositing the magnetic medium on the disk with an electroplating mechanism, in much the same way that chrome plating is deposited on the bumper of a car. The aluminum/magnesium or glass platter is immersed in a series of chemical baths that coat the platter with several layers of metallic film. The magnetic medium layer itself is a cobalt alloy about 1 µ-inch thick.

Thin-film sputtered media are created by first coating the aluminum platters with a layer of nickel phosphorus and then applying the cobalt-alloy magnetic material in a continuous vacuum-deposition process called sputtering. This process deposits magnetic layers as thin as 1 µ-inch or less on the disk, in a fashion similar to the way that silicon wafers are coated with metallic films in the semiconductor industry. The same sputtering technique is then used again to lay down an extremely hard, 1 µ-inch protective carbon coating. The need for a near-perfect vacuum makes sputtering the most expensive of the processes described here.

The surface of a sputtered platter contains magnetic layers as thin as 1 µ-inch. Because this surface also is very smooth, the head can float more closely to the disk surface than was possible previously. Floating heights as small as 10nm (nanometers, or about 0.4 µ-inch) above the surface are possible. When the head is closer to the platter, the density of the magnetic flux transitions can be increased to provide greater storage capacity. Additionally, the increased intensity of the magnetic field during a closer-proximity read provides the higher signal amplitudes needed for good signal-to-noise performance.

Both the sputtering and plating processes result in a very thin, hard film of magnetic medium on the platters. Because the thin-film medium is so hard, it has a better chance of surviving contact with the heads at high speed. In fact, modern thin-film media are virtually uncrashable. If you could open a drive to peek at the platters, you would see that platters coated with the thin-film medium look like mirrors.
AFC Media

The latest advancement in drive media is called antiferromagnetically coupled (AFC) media, which is designed to allow densities to be pushed beyond previous limits. Any time density is increased, the magnetic layer on the platters must be made thinner and thinner. Areal density (tracks per inch times bits per inch) has increased in hard disks to the point where the grains in the magnetic layer used to store data are becoming so small that they become unstable over time, causing data storage to become unreliable. This is referred to as the superparamagnetic limit, which has been determined to be between 30 and 50Gbit/sq. in. Drives today have already reached 35Gbit/sq. in., which means the superparamagnetic limit is now becoming a factor in drive designs.

AFC media consist of two magnetic layers separated by a very thin 3-atom (6 angstrom) film layer of the element ruthenium. IBM has coined the term "pixie dust" to refer to this ultra-thin ruthenium layer. This sandwich produces an antiferromagnetic coupling of the top and bottom magnetic layers, which causes the apparent magnetic thickness of the entire structure to be the difference between the top and bottom magnetic layers. This allows the use of physically thicker magnetic layers with more stable, larger grains to function as if they were really a single layer that was much thinner overall.

IBM has introduced AFC media into several drives, starting with the 2.5-inch Travelstar 30GN series of notearticle drives introduced in 2001, the first drives on the market to use AFC media. In addition, IBM has introduced AFC media in desktop 3.5-inch drives starting with the Deskstar 160 GXP. I expect other manufacturers to introduce AFC media into their drives as well. The use of AFC media is expected to allow areal densities to be extended to 100Gbit/sq. in. and beyond. Being a form of thin-film media, these platters would also look like mirrors if you could see them.

Hard Disk Formatting and Partitioning

A hard disk, however, requires two separate formatting operations. Moreover, a hard disk requires a third step, between the two formatting procedures, to write the partitioning information to the disk. Partitioning is required because a hard disk is designed to be used with more than one operating system. Using multiple operating systems on one hard disk is possible by separating the physical formatting in a procedure that is always the same, regardless of the operating system used and the high-level format (which is different for each operating system). Partitioning enables a single hard disk drive to run more than one type of operating system, or it can enable a single operating system to use the disk as several volumes or logical drives. A volume or logical drive is any section of the disk to which the operating system assigns a drive letter or name.

Consequently, preparing a hard disk drive for data storage involves three steps:














1. Low-level formatting (LLF)
2. Partitioning
3. High-level formatting (HLF)

Low-level Formatting

During a low-level format, the formatting program divides the disk's tracks into a specific number of sectors, creating the intersector and intertrack gaps and recording the sector header and trailer information. The program also fills each sector's data area with a dummy byte value or a pattern of test values. For floppy disks, the number of sectors recorded on each track depends on the type of disk and drive. For hard disks, the number of sectors per track depends on the drive and the controller interface.

Originally, PC hard disk drives used a separate controller that took the form of an expansion card or was integrated into the motherboard. Because the controller could be used with various disk drives and might even have been made by a different manufacturer, some uniformity had to exist in the communications between the controller and the drive. For this reason, the number of sectors written to a track tended to be relatively consistent.

Virtually all PATA, SATA, and SCSI drives use a technique called zoned-bit recording (ZBR), sometimes shortened to zoned recording, which writes a variable number of sectors per track. Without zoned recording, the number of sectors, and therefore bits, on each track is a constant. This means the actual number of bits per inch will vary. More bits per inch will exist on the inner tracks, and fewer will exist on the outer. The data rate and rotational speed will remain constant, as will the number of bits per track. Figure below shows a drive recorded with the same number of sectors per track.

sector
Standard recording, where the same number of sectors comprise every track.

A standard recording wastes capacity on the outer tracks because they are longer and yet hold the same amount of data (more loosely spaced) as the inner tracks. One way to increase the capacity of a hard disk during the low-level format is to create more sectors on the disks' outer cylinders than on the inner ones. Because they have a larger circumference, the outer cylinders can hold more data. Drives without zoned recording store the same amount of data on every cylinder, even though the tracks of the outer cylinders might be twice as long as those of the inner cylinders. The result is wasted storage capacity, because the disk medium must be capable of storing data reliably at the same density as on the inner cylinders. When the number of sectors per track is fixed, as in older controllers, the drive capacity is limited by the density of the innermost (shortest) track.

Drives that use zoned recording split the cylinders into groups called zones, with each successive zone having more sectors per track as you move outward from the center of the disk. All the cylinders in a particular zone have the same number of sectors per track. The number of zones varies with specific drives, but most drives have 10 or more zones. Figure below shows a drive with zoned-bit recording.

zone
Zoned recording, where the number of sectors per track increases within each zone, moving out from the center.

Another effect of zoned recording is that transfer speeds vary depending on which zone the heads are in. A drive with zoned recording still spins at a constant speed; because more sectors exist per track in the outer zones, however, data transfer is fastest there. Consequently, data transfer is slowest when reading or writing to the inner zones. That is why virtually all drives today report minimum and maximum sustained transfer rates, which depend on where on the drive you are reading from or writing to.

With SCSI, ATA, and SATA disks, however, formatting individual tracks with different numbers of sectors became possible because these drives have the disk controller built in. The built-in controllers on these drives are fully aware of the zoning algorithm and can translate the physical cylinder, head, and sector numbers to logical cylinder, head, and sector numbers so that the drive appears to have the same number of sectors on each track. Because the PC BIOS is designed to handle only a single number of sectors per track throughout the entire drive, a zoned drive must run by using a sector-translation scheme.

The use of zoned recording enables drive manufacturers to increase the capacity of their hard disks by 20%50% compared with a fixed sector-per-track arrangement. All modern hard disk drives today use zoned recording.
Partitioning

Creating a partition on a hard disk drive enables it to support separate file systems, each in its own partition.

Each file system can then use its own method to allocate file space in logical units called clusters or allocation units. Every hard disk drive must have at least one partition on it and can have up to four partitions, each of which can support the same or different type file systems. Three common file systems are used today:

  • File Allocation Table (FAT) This is the standard file system supported by DOS and Windows 9x/Me. FAT partitions support filenames of 11 characters maximum (eight characters plus a three-character extension) under DOS, and 255 characters under Windows 9x (or later). The standard FAT file system uses 12- or 16-bit numbers to identify clusters, resulting in a maximum volume size of 2GB.


Using FDISK, you can create only two physical FAT partitions on a hard disk driveprimary and extendedbut you can subdivide the extended partition into as many as 25 logical volumes. Alternative partitioning programs, such as Partition Magic, can create up to four primary partitions or three primary and one extended.

  • File Allocation Table, 32 bit (FAT32) An optional file system supported by Windows 95 OSR2 (OEM Service Release 2), Windows 98, Windows Me, and Windows 2000/XP. FAT32 uses 32-bit numbers to identify clusters, resulting in a maximum single volume size of 2TB or 2,048GB.

  • Windows NT File System (NTFS) The native file system for Windows NT/2000/XP that supports filenames up to 256 characters long and partitions up to (a theoretical) 16 exabytes. NTFS also provides extended attributes and file system security features that do not exist in the FAT file system.


Until the release of XP, FAT32 was by far the most popular file system. Because NTFS is native to XP, NTFS is now becoming more popular in newer systems. Still, the FAT file system is accessible by nearly every operating system, which makes it the most compatible in a mixed OS environment. FAT32 and NTFS provide additional features but are not universally accessible by other operating systems.

Partitioning normally is accomplished by running the disk-partitioning program that comes with your operating system. The name and exact operation of the disk partitioning program varies with the operating system. For example, FDISK is used by DOS and Windows 9x/Me for this task, whereas the DISKPART command or the Disk Management snap-in component of the Computer Management service is used with Windows XP. FDISK, DISKPART, and other disk-partitioning tools enable you to select the amount of space on the drive to use for a partition, from a single megabyte or 1% of the drive up to the entire capacity of the drive, or as much as the particular file system will allow. Normally, it is recommended to have as few partitions as possible, and many people (myself included) try to stick with only one or two at the most. This was more difficult before FAT32 because the maximum partition size for a FAT16 partition was only 2GB. With FAT32, the maximum partition size can be up to 2,048GB. Note that Windows 2000 and XP refuse to format a FAT32 volume over 32GB, even though they will recognize existing FAT32 volumes up to the 2,048GB limit.
High-Level Formatting

During the high-level format, the operating system writes the structures necessary for managing files and data on the disk. For example, FAT partitions have a Volume Boot Sector (VBS), two copies of a file allocation table (FAT), and a root directory on each formatted logical drive. These data structures enable the operating system to manage the space on the disk, keep track of files, and even manage defective areas so they do not cause problems.

High-level formatting is not really a physical formatting of the drive but rather the creation of a table of contents for the disk. In low-level formatting, which is the real physical formatting process, tracks and sectors are written on the disk. As mentioned, the DOS and Windows FORMAT command can perform both low-level and high-level format operations on a floppy disk, but it performs only the high-level format for a hard disk. Low-level formats of ATA and SCSI hard disk drives are performed by the manufacturer and should almost never be performed by the end user. The only time I do a low-level format of an ATA or SCSI drive is when I am attempting to repair a format that has become damaged (parts of the disk become unreadable), or in some cases when I want to wipe away all data on the drive

How Hard Disk Drive Work


The basic physical construction of a hard disk drive consists of spinning disks with heads that move over the disks and store data in tracks and sectors. The heads read and write data in concentric rings called tracks. These tracks are divided into segments called sectors, which normally store 512 bytes each.

tracknsector

The tracks and sectors on a disk.



Hard disk drives usually have multiple disks, called platters, that are stacked on top of each other and spin in unison, each with two sides on which the drive stores data. Most drives have one, two, or three platters, resulting in two, four, or six sides. The identically aligned tracks on each side of every platter together make up a cylinder. A hard disk drive normally has one head per platter side, with all the heads mounted on a common carrier device or rack. The heads move radially across the disk in unison; they cannot move independently because they are mounted on the same carrier or rack, called an actuator.

platter
Hard disk cylinders.

Originally, most hard disks spun at 3,600rpmapproximately 10 times faster than a floppy disk drive. For many years, 3,600rpm was pretty much a constant among hard drives. Now, however, most drives spin even faster. Although speeds can vary, modern drives normally spin the platters at either 4,200, 5,400, 7,200, 10,000, or 15,000rpm. Most standard-issue drives found in portable systems spin at the slower 4,200 or 5,400rpm speeds, with a few high performance models now available that spin at 7,200rpm. The 10,000 or 15,000rpm drives are normally found only in very high performance desktop-based workstations or servers, where their higher prices, heat generation, and noise can be more easily dealt with. High rotational speeds combined with a fast head-positioning mechanism and more sectors per track are what make one hard disk overall faster than another.

The heads in most hard disk drives do not (and should not!) touch the platters during normal operation. However, on most drives, the heads do rest on the platters when the drive is powered off. In most drives, when the drive is powered off, the heads move to the innermost cylinder, where they land on the platter surface. This is referred to as contact start stop (CSS) design. When the drive is powered on, the heads slide on the platter surface as they spin up, until a very thin cushion of air builds up between the heads and platter surface, which causes the heads to lift off and remain suspended a short distance above or below the platter. If the air cushion is disturbed by a particle of dust or a shock, the head can come into contact with the platter while it is spinning at full speed. When contact with the spinning platters is forceful enough to do damage, the event is called a head crash. The result of a head crash can be anything from a few lost bytes of data to a completely ruined drive. Most drives have special lubricants on the platters and hardened surfaces that can withstand the daily "takeoffs" and "landings" as well as more severe abuse.

Some newer drives do not use CSS design and instead use a load/unload mechanism, which does not allow the heads to contact the platters, even when the drive is powered off. First used in the 2.5-inch form factor notearticle or laptop drives, where resistance to mechanical shock is more important, load/unload mechanisms use a ramp positioned just off the outer part of the platter surface. When the drive is powered off or in a power-saving mode, the heads ride up on the ramp. When powered on, the platters are allowed to come up to full speed before the heads are released down the ramp, allowing the airflow (air bearing) to prevent any head/platter contact.

Because the platter assemblies are sealed and nonremovable, the track densities on the disk can be very high. Hard disks today have up to 96,000 or more tracks per inch (tpi) recorded on the media (for example, Hitachi Travelstar 80GN). Head disk assemblies (HDAs), which contain the platters, are assembled and sealed in clean rooms under absolutely sanitary conditions. Because few companies repair HDAs, repair or replacement of the parts inside a sealed HDA can be expensive. Every hard disk ever made eventually fails. The only questions are when the failure will occur and whether your data is backed up.

Tracks and Sectors


A track is a single ring of data on one side of a disk. A disk track is too large to manage data effectively as a single storage unit. Many disk tracks can store 100,000 or more bytes of data, which would be very inefficient for storing small files. For that reason, tracks are divided into several numbered divisions known as sectors. These sectors represent arc-shaped pieces of the track.

Various types of disk drives split their disk tracks into different numbers of sectors, depending on the density of the tracks. For example, floppy disk formats use 836 sectors per track, although hard disks usually store data at a higher density and today can have 900 or more sectors per track physically. The sectors created by the standard formatting procedure have a capacity of 512 bytes, which has been one constant throughout the history of the PC. In order to be compatible with most older BIOS and drivers, drives will usually perform an internal translation so that they pretend to have 63 sectors per track when addressed in CHS (cylinder, head, sector) mode.

The sectors on a track are numbered starting with 1, unlike the heads or cylinders that are numbered starting with 0. For example, a 1.44MB floppy disk contains 80 cylinders, numbered 079, and two heads, numbered 0 and 1, whereas each track on each cylinder has 18 sectors numbered 118.

When a disk is formatted, the formatting program creates ID areas before and after each sector's data that the disk controller uses for sector numbering and for identifying the start and end of each sector. These areas precede and follow each sector's data area and consume some of the disk's total storage capacity. This accounts for the difference between a disk's unformatted and formatted capacities. Note that most modern hard disks are sold preformatted and advertise only the formatted capacity. The unformatted capacity is usually not mentioned anymore. Another interesting development is that many new drives use what is called No-ID sector formatting, which means that the sectors are recorded without ID marks before and after each sector. This means that more of the disk can be used for actual data.

Each sector on a disk normally has a prefix portion, or header, that identifies the start of the sector and contains the sector number, as well as a suffix portion, or trailer, that contains a checksum (which helps ensure the integrity of the data contents). Many newer drives omit this header and have what is called a No-ID recording, allowing more space for actual data. With a No-ID recording, the start and end of each sector are located via predetermined clock timing.

Each sector contains 512 bytes of data. The low-level formatting process normally fills the data bytes with some specific value, such as F6h (hex) or some other repeating test pattern used by the drive manufacturer. Some patterns are more difficult for the electronics on the drive to encode/decode, so these patterns normally are used when the manufacturer is testing the drive during initial formatting. A special test pattern might cause errors to surface that a normal data pattern would not show. This way, the manufacturer can more accurately identify marginal sectors during testing.

The sector headers and trailers are independent of the operating system, the file system, and the files stored on the drive. In addition to the headers and trailers, gaps exist within the sectors, between the sectors on each track, and also between tracks, but none of these gaps contain usable data space. The gaps are created during the low-level format process when the recording is turned off momentarily. They serve the same function as having gaps of silence between the songs recorded on a cassette tape. The prefix, suffix, and gaps account for the lost space between the unformatted capacity of a disk and the formatted capacity. For example, a 2MB (unformatted) floppy has a formatted capacity of 1.44MB, and an older 20GB unformatted capacity hard disk (for instance, a Quantum Fireball LCT20) has a capacity of only 18.3GB when it is formatted. Because the ATA and SCSI hard disks you purchase today are low-level formatted at the factory, the manufacturers now advertise only the formatted capacity. Even so, nearly all drives use some reserved space for managing the data that will be stored on the drive.

How to Save Data When Your Hard Disk is Dying

What if you’re in a situation where you feel a drive failure could happen at any moment, but you simply don’t have a means of backing up the drive? I saw this recently with a system that had become too unstable to get through something as disk intensive as a backup; the system died each time someone tried to record files to a CD-R.

In a situation where you have a small number of files you desperately need to save off the hard drive, copy them to a floppy disk or a Zip disk. If you have access to a file compression utility like WinZip or FreeZip, archive up to 1MB of files and send them to yourself in an e-mail; don’t retrieve that e-mail until you come out on the other end of your drive problem. Most web-based e-mail sites allow for file attachments.

If the PC with the failing drive is on a network, move as many important files to a drive on another system where you have access (the drive or folders on the other PC gives you share-level access to save files to them).

Online Backup Services


Online backup services provide you with an account and special software or a browser-based interface for uploading files to their storage servers for an annual fee. The goal of these services isn’t to upload the entire contents of your hard drive but to store strategic files that you can’t afford to lose or that you want stored in a second location accessible through the Internet. Many business travelers subscribe to such services so that if something happens to their laptop while they’re on a trip, they can always log onto the backup service from a borrowed PC or laptop from virtually anywhere and grab the files they need. The following sites provide online backup storage:

@Backup (www.@backup.com) You download and install their software, which provides an easy-to-use interface for uploading files to their storage servers. Pricing here starts at an annual service fee of $49.95 for 50MB or $995 for 2GB. At the time this book was being prepared for release, @Backup was offering a 30-day free trial with annual signup.

Virtual Backup (www.virtualbackup.com) Virtual Backup offers a Simple Plan that allows you to store up to 50MB of files at an annual rate of $39.95 or 100MB for $79.95 a year. Like @Backup, they offer a 30-day free trial.

A Quick E-mail Trick


Here’s a quick trick I learned when I was rushing to secure a really important document for work on a drive that sounded like it would grind itself to death at any moment.

If your word processor or other application has a Send To feature on the File menu (Microsoft Word is one program that has it) and you currently have access to the Internet, send a copy of the file to yourself through e-mail directly from the application.

Let’s pretend I’m furiously trying to finish this chapter on a PC where the drive appears to be having problems. Naturally, I don’t want to take the chance of losing the work, so I would take these steps:

  1. Save the most recent version of the file. If that’s not possible, proceed to step 2.

  2. In Word, I choose File Ø Send to Ø Mail Recipient (you can also choose Mail Recipient as Attachment, if preferred).

  3. When my e-mail software opens, I address the file to myself and click Send. (If you used the Mail Recipient as Attachment option in step 2, you’ll have to specify the name and location of the file you want to send.)

  4. Later, once the hard drive crisis is corrected or from another PC, I retrieve my e-mail and my attached file.


Once your important data is saved in a retrievable format, it’s time to start checking the source of the hard drive problem.

When BIOS can not Detect the Hard disk


Your hard disk is SMARTer than you think, at least in terms of the Self-Monitoring, Analysis, and Reporting Technology (SMART) built into it.

Hard disks now contain detailed information about themselves (type of drive, ID number) contained in programmed chips on the drives, which helps both BIOS and Windows know what type of drive they’re working with. This information makes it easier for the drive to be detected by the BIOS, to be seen as part of the essential hardware inventory when the COMPUTER is started. For those of us who remember a time when adding a new hard disk meant an hour or two of complicated debugging commands, this stored drive information makes life much easier.

But damage to the recorded information, as you might see with a power surge, extreme overheating, or when you forget to disconnect the COMPUTER’s power before you plug in a new drive, can make it impossible for the BIOS to read these identifying details. BIOS may not even realize a drive is connected at all.

The BIOS may not recognize a new drive when the drive capacity is larger than your BIOS version is designed to support. Some Pentium II and III systems, for example, may have problems when you add a 20GB or larger hard disk simply because their BIOS hasn’t been updated since these systems were first built in 1997–1999. To resolve this problem, do one of the following:

  • Obtain and apply a BIOS update

  • Use drive/BIOS overlay software


Another problem with new drives is improper cable connections and improper jumper settings can keep the BIOS from detecting the hard disk. However, once a drive has been installed and detected, the BIOS should see the drive each and every time your COMPUTER starts. If it doesn’t (and outside of some of the disaster conditions such as smoke or a terrible sound from the drive), you should

  1. Restart your COMPUTER.

  2. As the COMPUTER restarts, follow the on-screen directions to enter BIOS Setup (as in, “Press <this key> to Enter Setup”).

  3. Locate your drive listings (usually on the general information screen).

  4. Click Auto Detect (if available) to see if this picks up the drive.


Also check your manufacturer’s web site for other suggestions for getting the BIOS to recognize the drive. Some web sites have specific settings for the drive that may help get it recognized again if the actual hardware on the drive itself isn’t damaged.

Then you must rule out a loose data ribbon cable or dust interposed between the drive and the ribbon cable interface, or a loose power cable. If no power is getting to the drive, the power light on the drive should remain dark.

Manufacturer-Supplied Disk Tools and Diagnostics


If you installed drive-management software when you installed your problematic hard disk or you have a disk from the manufacturer containing a diagnostics tool, run this software to see what it reports. If you have to call the manufacturer for support on the drive, you may be asked to provide the results from the diagnostics testing.

Checking Related Issues


What Did You Do Last?


Stop and think: What did you do during the last session the drive responded normally? For example, did you

  • Modify drive settings in the BIOS Setup?

  • Install drive software or utilities? (A common culprit is a utility written for a different version of Windows or one using a different file system.)

  • Try unsuccessfully to repartition or reformat your drive?


If available, check the troubleshooting section of any documentation that exists for anything you did install. You might be able to glean from it what went wrong.

In addition, try to reverse whatever you did to see if this rectifies your current problem.

Did It Suffer a Disaster?


Do you know if the hard disk suffered some type of physical disaster? Was the COMPUTER on when you lost power in a storm or experienced a power surge (especially if the COMPUTER wasn’t protected by a surge suppressor or UPS)? If so, it’s more likely, but not certain, that there has been actual hardware-level damage. The same is true if you tried to connect the drive with the COMPUTER turned on.

That damage can be there even if it’s not immediately visible. For example, even if a COMPUTER itself does not get touched by a fire, the sheer heat of a fire (not to mention the smoke and water damage) can damage components like a hard disk. This can be true even when the heat doesn’t melt or soften the plastic pieces in and around the COMPUTER.

Are You Using Drive-Overlay Software?


Drive-overlay software is often packed with new hard disks to allow COMPUTERs with slightly older BIOSes to work with that hard disk and recognize its full capacity.

When drive-overlay software is preventing a hard disk from performing, you’ll typically see an on-screen message telling you to insert the recovery or boot disk for that overlay software. This disk is likely one you created when you installed the drive and configured the drive-overlay software.

If your current situation involves error messages that reference that drive-overlay software, check the software’s documentation and/or the manufacturer’s web site for troubleshooting notes (another good use for a spare Internet-ready COMPUTER). You need to resolve the drive-overlay issue before you determine whether the hard disk itself is having a problem.

Have You Scanned for Viruses?


If you’re seeing a drive light for the hard disk but it’s not responding or it’s giving you an error message, use a floppy disk-based virus scanner.

Viruses can do a number of nasty disk-based tricks, including overwriting the master boot record (MBR) needed to boot the hard disk, deleting core operating system files, and scrambling drive partitions.

How Is Your COMPUTER Power Supply?


While this is a long shot, it’s possible that your COMPUTER power supply is failing and needs replacement or is underpowered so it doesn’t have enough juice to supply to this drive along with the other components that require power.

A few of the ways I’ve seen my power supplies fail was to watch one or two devices (usually drives) that formerly were powered up fine suddenly receive no power while everything else operated normally. It took changing out the power supply (usually as a last-ditch effort because I couldn’t figure out what else could be responsible) each time before I got power back to everything that needed it.

Working with Damaged Files in Microsoft Office


Since Microsoft Office, or one of its main components such as Word, is so widely used, let’s discuss the recovery options within Office that can help you salvage some or all of a damaged file.

If you’re using an older version of Office, you won’t have these advanced recovery options available to you. But for other users, these options can often make the difference between a few minutes of fixup vs. re-creating an entire file from scratch.

Office 2000 was the first version of Office to include features for repairing a damaged file. Office XP includes significant improvements to these features. But the true gem of both versions is an auto-recovery option you enable to save copies of your work and to recover the last versions automatically for you in the event of a crash or power outage that closes out your open Office files.

For this, you need to enable the auto-save feature, because it works in concert with the recovery feature in Office to store copies of your file frequently and automatically as you work. Once Office—and especially Word—loads again following a crash, the recovery feature tries to load your files from those saved copies.

To enable this feature, take these steps:

  1. From Word, click Tools Ø Options Ø Save.

  2. Click to check Always Save Backup Copies (Office XP/Word 2002 users will see Always Create Backup Copy).

  3. Click to check Save AutoRecover Info Every and then specify the time period (I would recommend every 3 to 6 minutes). Click OK.


option

While this works in Office 2000, it’s improved greatly in Office XP to the point where it’s rare for me to lose more than a few sentences after a system crash. The moment I load Word after such a crash, a Document Recovery window pops up showing me the files it has recovered. I usually don’t need to do a thing except check the recovered documents and save them as needed. I wish all programs were so accommodating.

One last thing about the Document Recovery window in Word/Office XP: You can select a recovered file from this window and click Show Repairs to learn exactly what changes were made to the file in trying to recover, repair, and make it available to you. The information located here may give you hints as to problems in formatting, for example, that you should check in the document before you save it again.

If all else fails, purchase and download software specifically written to extract data from damaged Office files. One of the best-known sites for this type of software is Office Recovery (www.OfficeRecovery.com). At this site, you’ll see that not just Microsoft Office is covered; you can get tools to help with programs such as Outlook Express and Microsoft Money.
Using Microsoft Office Application Recovery

New in Office XP is Microsoft Office Application Recovery, a tool designed to get into a non-responsive Office application and recover the files that are currently open. This tool works not just for Word, but also for Excel and PowerPoint as well.

If you get into this situation with one of the listed Office programs, simply run the Application Recovery tool by choosing Start Ø All Programs Ø Microsoft Office Tools Ø Microsoft Office Application Recovery.

This won’t necessarily work every time to recover all open and unsaved work, but it’s certainly worth a shot, especially if you’re inclined to simply restart the machine and potentially lose that open work anyway.

The main problems which cause hard disk data loss

Data Recovery is becoming more important by the increasing degree of data loss, also called data loss.

Despite technological advances in the reliability of magnetic storage media, data loss continues to rise, making data recovery has become more important than ever.

Our data recovery specialists have three trends can be traced, which leads to the increase of data loss.

1. More data are stored in 'small areas'. Today's hard drives store 500 times more data than it was stored on the hard drives of a decade ago. Increasing the storage capacity increases the impact of data loss and makes the mechanical precision more critical of the hard disk.

2. Data are more task-dependent and time become Hospital patient data, a school assignment, personal finance and tax information, payment of salaries, etc.. Users now electronically store more information than ever before. The loss of mission critical data, a staggering and sometimes even a devastating effect on the financial, legal and productivity ramifications of both corporate and home users.

3. Backup tools and techniques are not 100% reliable. Most computer users rely on backups as their safety net in case of loss of data (recommended in practice). Research shows that 80 percent of the customers who were dealing with data loss, do regular backups of their data had been. Backups assume that hardware and storage media are working, the data are intact and that recent your backup is good enough for a full recovery. In reality, hardware and software failures and backups do not always sufficient and recent data.

Key causes of data loss:

Hardware or System Malfunctions (44% of all data loss)
A head crash of the hard disk is the most common form of an error occurring in the hard disk. More than 44% of the errors resulting from hardware failures in the disk. The head of the hard drive is the most delicate part. The hard disk platter rotates namely 1 seconds 150 times around the head and moves above the platter with only a submicro distance between them.

For comparison, a Boeing constantly fly half millimeters above the ground!

Any disturbance can cause a head crash that leads to a broken harddisk. Even dust particles between the platter and the head come to serious injury to the head which give the hard drive is inaccessible.

Symptoms
• error message stating that the device
recognized
• Previously accessible data suddenly gone
• Computer hard drive does not
• ticking or rattling noises
• Hard disk spins not

Examples
• Power cuts
• Harddisk crash / crash Head
• Controller errors

Preventive measures
• Protect electrical components by using computers in a dry, shaded and dust-free area
• Protect against power surges with an uninterruptible power supply (UPS)
• Do not shake or remove the covers on hard drives or tapes.

Human errors (32% of all data loss)
Another major threat to the integrity of the data, the risk of humans. This type of damage occurs in two forms: intentional and unintentional. Individuals or groups can deliberate harm, with malice as the ultimate goal.

The best defense against this form of threat is a very aggressive safety program that includes adequate separation of data and access only granted based on need. For employees who have access and modify sensitive information, training is often the best preventive measure against accidental loss.

Symptoms
• Previously accessible data suddenly gone
• message similar to "File not found"

Examples
• accidentally delete or erase
• Intentionally remove or delete
• Damage caused by a fall

Preventive measures
• Never try an operation, like installations or repairs, if you do not have experience
• Avoid moving your computer, especially when it is operating.
• Installing security software

Software Corruption (14% of all data loss)
There are times when data loss occurs due to a software malfunction. Software, we work with, not working properly because the programs 'freeze' and we are unable to store the data so the data loss.

Sometimes some software can corrupt the operating system which also leads to loss of data. Data recovery software can help recover and restore lost data.

Symptoms
• System messages relating to memory errors
• software application can not load
• error message indicating that the data are corrupted or inaccessible

Examples
• Corruption caused by diagnostic or repair tools
• Failed backups
• Configuration complexity

Preventive measures
• Back up data regularly
• Use diagnostic utilities with caution.

Computer Viruses (7% of all data loss)
Viruses can also cause a system error. Some viruses come together with one or another program via the internet within our hard disk. These viruses have loaded themselves into the operating system, the file system is corrupt and therefore we end up in a data loss situation.

Symptoms
• Blank screen
• Strange and unpredictable behavior
• "File not found" message that announces that virus on the screen

Examples
• Boot sector viruses
• File infecting viruses
• polymorphic viruses

Preventive measures
• Use a good anti-virus package
• Obtain software from trusted sources
• Scan all incoming data, including packaged software, for viruses.

Natural disasters (3% of all data loss)
Natural disasters such as earthquakes, floods, fires and lightning are the different ways we experience loss of data. Floods cause such great damage to the hard disk because a large amount of moisture accelerates the corrosion process and thus brings damage to the electronic circuit board. Professional Data Recovery Service companies are able to recover data from all types and all situations of data loss.

Symptoms
• While floods and earthquakes have obvious symptoms, avalanches and lightning often give no evidence.

Examples
• Fires
• Floods
• Avalanches

Preventive measures
• Store tested backups in a different location
• Do not save critical data in an alluvial area
• Install a UPS.

From our years of experience shows that, in most cases of data loss, data can be recovered, by a hard disk repair regardless of the cause of the loss. So never think that your valuable data is lost forever.

Hard Disk Data Recovery

Imagine for - day and night working on a very important project and it is almost done ... but if you just go away for a break, your computer screen is black when you return.

The whole project is ruined and you are left with nothing. What conclusion would you draw for the cause of the sudden black-out on your computer?

• Could it just be an unexpected system shutdown? - Try to restart, which you can do 2 to 3 times.
• Would it be a loose connection? - Check the connections and push firmly.

Would it be a disk error?

First check your hard disk controller, which can also cause this condition. You can always try to switch from your hard drive ide1 to IDE2om to see if this resolves the issue.

If the problem persists, remove the disk from your computer and connect it to another computer. If it still does not work, you can expect your hard drive is broken.

So this means that all your important data, files, pictures, your favorite music, e-mails and all other important things stored on your computer, you lost.

At this point, it is important to remain calm and not panic! It may be that all data is still on!

You can try different options to recover the data:

1. Test it on another computer system: Once you see your hard drive is not working or some weird noises from your hard disk, remove the hard drive and test it on your friend's computer. If the hard drive running at half computer, there is no problem, but if not, then it is time to choose between data recovery software or data recovery services.

2. Hard Drive Recovery Software: There are many hard drive data recovery software tools for recovering the lost data. Many companies offer data recovery software file recovery tools to recover data.

You can use one of the many data recovery software that try often available as a free demo downloads. Data recovery software scans your hard drive and restores every bit corrupt the data from your damaged hard drive. Try the demo and then buy the full version of the data recovery software that works best for your problem. The software is usually available at a reasonable price and does the work, recovery of data, efficiently and effectively.

3. Hard Drive Recovery Services: Hard drive recovery services are advantageous in situations where the data recovery software is unable to recover the data, such as the corruption level of the hard disk is too high. In this case the data recovery performed by a data recovery technician in the Class 100 cleanroom.

This "clean rooms" are equipped with high security and biometrics are the best and safest place to run a data recovery, because sharp observation and a proper environment required for this process.

Hard drive and hard disk recovery services are also ensuring data recovery, even in complex cases where the data was inaccessible because a;

- Hard disk crash
Burned Burnt hard drive disk
- Computer system fell from a height
- Corrupt hard drive due to sabotage or fraud

And there are endless reasons and situations which can damage your hard drive.

Heavy burden

In general, these services are based on quotes from the media type, the extent of the corruption of your hard drive and the data that you want to recover.

These data recovery services can cost thousands of dollars, leading to heavy loads. However, can in most cases the data are effectively recovered by using this data recovery services.

However, if you do not want one company to run for the recovery of your data, always ensure the implementation of regular data backups, so you a stress free and secure global data create for yourself.

Choosing between data recovery software and undelete programs

Data recovery software and undelete programs for some products seem similar, but different world view of the possibilities:
data recovery software has multiple functions to restore the system from different angles, while the fundamental undeletes primarily designed to retrieve deleted data, although the detailed description that you will not say.

Tracking the price tag

The quick and easy way to distinguish between recovery products, without any technical issues you have to learn, is investigating how much they cost.

Data recovery software programs that are priced under fifty euro will have an undelete utility - most of the time, the price is around forty euros. The better quality recovery software programs can help in more complex data issues, and those found in the more expensive price - eighty euro, the more sophisticated programs can run into the hundreds of euros.

Keep in mind, any recovery companies tend to sell part of their all-in-one special packages, because many people are looking for a program to be used only once. In any case, check whether the product you are considering to purchase, will help your specific problem.

For the technically savvy ...

Knowing the problem can provide insight to the solution. First, here are some background notes:

1. Deleted files are files that are intentionally and discarded in the trash stream.
2. Lost files due to emptying the Recycle Bin on the computer, a virus, accidental format, partition or a boot problem.
3. Corrupt data files contain distorted when you open them.
4. Corrupted files contain modified data, but one of them could read. Symptoms appear at number three, but in technical terms they are different.

Undelete Recovery Program
The big difference

Although both recovery tools are able to recover data, the main difference that separates the two as follows: data recovery software can effectively recover data and a file system intact is not rebuilding, so your data can be recovered - while undelete recovery programs can not.

Moreover, a file system intact means that all components, which merge the individual files, not damaged.

So, note to # 1 and # 2 sometimes you need an undelete program. In all other cases, data recovery software is the answer.

If these technical terms are not useful for you, and you do not understand the difference between all the data recovery tools available on the market, hold the line on the price in mind when choosing the right data recovery utility.

Choosing expert help

Well - as disk data recovery software is unable to retrieve your files, you can contact a hard drive data recovery expert to recover the data back. It will then cost more, but if the data recovery software can not help, a professional is the last hope.

Disaster Recovery best practices

Research shows that most companies affected by a catastrophic event, without a data disaster recovery plan to have. Go out of business within two years. Even a basic disaster recovery plan will increase chances of data recovery.

Disaster Recovery (Data Recovery Disaster) Tips:

1. Keep your system passwords at least two separate secure locations. Only one of them in the same building as your IT equipment. At least two employees should have access to these codes.

2. Document, Document, Document! Make sure the entire process of your company again in the air to get committed and includes the locations of the other critical systems and hard drives. Make sure key personnel are familiar with these disks.

3. Establish an automated system to inform key personnel to bring the disaster. These employees must be thoroughly trained so that basic disaster recovery / backup jobs can run unattended. You may do this through an agreement with third provider.

4. Practice your disaster recovery plan on a quarterly basis or more frequently. This not only sharpens the skills of your disaster recovery team, but it will also make new employees familiar with the procedure, and ensure that your disaster recovery strategy is updated by revealing potential problems with new equipment or software.

5. No matter how good your disaster recovery plan, it can not recover data if you neglect to back up save. Make sure there is a routine to regularly back up data to, and make sure that this is done.
By at least one RAID level 5 (RAID Level 10, if the budget allows) you can ensure that duplicate data has a high error tolerance. Build as much redundancy in your system for the removal of some points of failure. This includes a multi-path route data to the system, so you still have access to your data as a path no longer works.

6. Rule by additional spare hard drives already in the system to place, or at least physically present in the same space as your storage system.

7. A tape archive strategy is crucial. Tapes on a daily basis are used, every six to nine months to be replaced to prevent deterioration - backups are useless if they can not be recoverable. Other tapes should be replaced on a regular basis and based on the frequency of use. The ability to back up at a different location to store almost any price! A fireproof safe is not an alternative to off-site location.

8. Take the best, longest life, the most you can get uninterrupted power supply. Make sure that you have a battery backup for the contents of the cache memory.

9. Not neglect to protect yourself against any theft, vandalism and malice of an employee, they can be as disastrous as anything else. Make at least for the door to your data / server room is locked, day and night.

10. An automatic closing fire door to the data / server room is fire and smoke from the room for a surprisingly long time.

Common errors in Disaster Recovery Plans.

Most disaster recovery plans that fail do so by the lack of data back-ups, lack of regular exercise, or lack of documents.

A simple but documented plan with recent back-ups and trained personnel will work better, then let a sudden regime must take one of these points.

3 Steps to Backup your Data online

Data back-up - A simple 3-step guide to choosing the best backup solution.

If you long time trying to figure out what the best solution for your computer's data back-up, you know how frustrating it can be to concentrate and continue searching.

It seems that every other website you pull one million different directions, and more often than not remain behind you frustrated because you are closer to the answer of a back-up solution are bold.

This article provides a very simple, straightforward step-by-step approach to ensure that you get frustrated and also helps you find the perfect data backup solution that meets your needs.

1. Determine the importance and value of the information you want to back up.

This is a crucial first step if you do not want to pay too much for a service you do not really need. I'm sure someone has already tried a € 300 monthly data back-up plan to sell, and I tell you that there was 99.9% of the average computer user is priced too high.

Find out how much of everything on your computer worth to you, both financially and emotionally. I know I have pictures on my computer where I stand absolutely sure that my heart will be broken if anything happened to them.

Correct completion of this first step is probably the biggest hurdle to overcome.

2. Find out how much you can spend per month for your back-up.

Based on the number where you came from the first step, and also by how much space you have in your budget, you can find out how much you are able to spend a month for a data backup service provider.

If you absolutely nothing of any value on your computer, would a regular CD backup sufficient. However, this is the only case where I back-up method if this advise.

For those who have decided that they have some pretty valuable things on their computers, has been the best option to another location to back up the data to. For this method, you need a monthly subscription of a service purchase. This is a few dollars to several hundred dollars a month. However, remember that you often cost more if your data is lost.

A back-up service for around 30 per month, from my experience, more than sufficient for the needs of most computer users will have. A typical feature in this price range is an automatic back-up, the care deprives the equivalent of forgetting to back up data to your computer.

3. For special offers that are offered.

This is the part where you take the step to go to a purchase of a backup plan. You'll see that most experts recommend this method of data backup, so it is really one of the best ways to ensure that your data will be secure.

When searching, look for a company that has an offer for you to participate. Some companies will send you a free trial offer of 30 days, to test their program like it.

The choice for a company that offers such trials take away any risk of your purchase, because you know that if the service does not like you'll never have to pay for the expiry of that 30 days.

Choosing the right data back-up plan is one of the most critical decisions that every computer owner needs to make to prevent data loss. So enter your first review and I am sure that the right data backup service that will meet your needs.
