When drives and storage media become unreadable by the usual methods, it is often possible to recover data using specialized [[software]].

Damaged data generally falls into one of two categories:
* the directory listing can be read, and filesystem-checking utilities (such as scandisk in [[Microsoft Windows]] and [[fsck]] in [[Linux]]) report no errors, but attempting to read files results in error messages, time-outs, or bad data
* directory listings are unavailable or damaged

Different software is appropriate depending on which of the two situations is occurring.
