ddrescue is a data recovery tool. It copies data from one file or block device (hard disc, cdrom, etc) to another, trying to rescue the good parts first in case of read errors. 1


ddrescue can be installed with the Pakfire web interface or via the console:

pakfire install ddrescue


There is no web interface for this Addon. To run this Addon open the client console or terminal and access the IPFire box via SSH.

To obtain a list of possible options:
ddrescue -h

The output is similar to this:

[root@ipfire ~]# ddrescue -h
