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.

Ddrescuelog is a tool that manipulates ddrescue mapfiles, shows mapfile
contents, converts mapfiles to/from other formats, compares mapfiles,
tests rescue status, and can delete a mapfile if the rescue is done.

The homepage is at http://www.gnu.org/software/ddrescue/ddrescue.html


Changes in this version:

  * The 'current_pass' field has been added to the mapfile. This allows
the copying phase to resume instead of restart from pass 1. It also
allows the retrying phase to resume in the same direction it was
interrupted.

  * Two new passes have been added to the copying phase.
Sometimes there is a significant difference in read speed and likelihood
of data recovery between blocks skipped due to slow areas, and blocks
skipped due to read failures. Two passes have been inserted after pass 2
that read the blocks skipped due to slow areas (if any) before the final
sweeping pass (which now is pass 5).

  * The '--cpass' option now accepts ranges of passes; '--cpass=1-4'.

  * The minimum read rate of good non-tried areas is no longer reduced
after each pass, and now only affects passes 1 and 2.

  * During the trimming phase, if any edge of a non-trimmed block is
already adjacent to a bad sector, it is considered as already trimmed
and is not trimmed again.

  * The 's' multiplier may now be appended to any of the other
multipliers. For example, 'ks' = kilosectors (1000 * sector_size).
