Version 1.12-1 of ddrescue has been uploaded.


Description from README:
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.

The basic operation of ddrescue is fully automatic. That is, you don't
have to wait for an error, stop the program, read the log, run it in
reverse mode, etc.

If you use the logfile feature of ddrescue, the data is rescued very
efficiently, (only the needed blocks are read). Also you can interrupt
the rescue at any time and resume it later at the same point.

Ddrescue is also able to selectively overwrite parts of the output file,
which has a number of interesting uses like wiping data, marking bad
areas or even, in some cases, "repair" damaged sectors.
