"It’s common wisdom that deleted files can’t be recovered from solid-state media, only from traditional mechanical hard drives. But this only applies to internal drives — USB flash drives and external solid-state drives are vulnerable to file-recovery attacks.
On the one hand, this can be good news — you can recover files you accidentally deleted from such drives. On the other hand, other people can recover your sensitive deleted data if they get access to these drives."I've sort of known this for a long time since there is a lot of freeware which will recover images from camera memory. I never really put two and two together that files deleted from SSD drives are unrecoverable.
