computing: software: data recovery

Overview

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.

Directories Ok, Files Bad

  • SpinRite is an excellent tool for recovering damaged data on otherwise apparently-healthy drives.
