What does ddrescue do?

GNU 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. So, every time you run it on the same output file, it tries to fill in the gaps without wiping out the data already rescued.

How do you use DD rescue?
