Frequently we wish to recover data from a disk drive that is malfunctioning. In these cases it is necessary to use techniques that can recover bad data.

One popular program for recovering bad data is [[SpinRite]]. This program works by turning off the disk drive's own data recovery technology and repeatedly re-reading each ''bad'' sector, with the hope that a good read may eventually happen.

The [[dd_rescue]] program can't recover from ''bad'' sectors, but it can skip around a disk and recover data that is still mostly good. [[dd_rescue]] reads the disk forwards until it finds an error; it then goes to the end of the disk and reads backwards. The [[aimage]] advanced disk imager implements a similar algorithm.
