fsck is not just for failing hard drives. fsck is used any time you
want to check a disk (may it be ssd, optical, magnetic) for any kind of
errors or inconsistencies. It's a standard part of any UNIX toolkit.
On Linux systems with ext2/3, you'll see lost+found, which is where
stuff ends up if it can't be connected to an actual file entry. Sounds
exactly like what those FSCK files are - DOS used to do this with scandisk.
