"Several years ago, I experienced a hard drive failure. I was at work when my laptop suddenly started to act particularly strange. First, I thought it was because I had too many windows open and the RAM was full, but when the problems persisted after a reboot, I knew it was more than that. I immediately started to back up recent files. About half an hour later, the hard drive failed audibly and the laptop wouldn’t boot anymore.
Thank God I had backups! Except that I didn’t have backups of everything. Just weeks earlier my backup drive had reached capacity. To back up important work files, I had decided to delete my personal photos. The irony was that I had already purchased a new external drive, but had not taken the time to back up my photos. Now they were lost and I was devastated.
Over the next couple of weeks I researched ways to recover the data and considered doing everything under the sun — and did most of it — to revive the old hard drive. I eventually did recover my data, but not in the way you would expect. If your hard drive has failed physically, maybe this little guide can help you or at least give you some hope. So roll up your sleeves and get to work. . . ."
Not a particularly unique article it does give some ideas about how to replace the motherboard or "PCB" of the drive, which you don't find in most articles of this sort.
