Ddrescue
From MEPIS Documentation Wiki
GNU ddrescue is a data recovery tool. It copies data from one file or block device (hard disc, cdrom, etc) to another, trying hard to rescue data in case of read errors.
Usage: the essential syntax is simple, just type as root:
ddrescue <drive one> <drive two>
For details, look at the man page, and full documentation can be had by pasting info:/ddrescue to the location line in konqueror. Or you can type at command line:
info ddrescue
Note that you may have to install the command info first.
