GNU ddrescue data recovery tool copies data
from one file or block device (hard disk,
CD-ROM, etc.) to another, trying to rescue
the good parts first in case of read errors.
GNU ddrescuelog is a tool that manipulates
ddrescue logfiles, shows logfile contents,
converts logfiles to/from other formats,
compares logfiles, tests rescue status, and
can delete a logfile if the rescue is done.
