GNU ddrescue is a data recovery tool. It copies data from one file or block device (hard disk, CD-ROM, etc.) to another, trying hard to rescue data in case of read errors. GNU ddrescuelog is a tool that manipulates ddrescue logfiles, shows logfile contents, converts logfiles to/from other formats, compares logfiles, tests rescue status, and can delete a logfile if the rescue is done.
Release Notes: The option "--fill" has been renamed to "--fill-mode". The option "--generate-logfile" has been renamed to "--generate-mode". During the copying phase, failed blocks containing one sector are marked as bad-sector instead of as non-trimmed. This avoids trying a sector twice when a cluster size of 1 is used. "configure" now accepts options with a separate argument.
Release Notes: This release adds the new option "-w, --ignore-write-errors", which makes fill mode ignore write errors. This is useful to avoid ddrescue exiting because of new errors developing while wiping the good sectors of a failing drive.
Release Notes: Ddrescuelog no longer says that the logfile does not exist when it exists but is empty. The manual now explains that only whole sectors can be read when "direct disc access" is used.
Release Notes: The option "-l, --logfile-size" has been added. Trimming is now done from both edges of each non-trimmed block. The largest blocks are trimmed first. The largest blocks are now split first until logfile reaches "--logfile-size" entries.
Release Notes: The option "--sector-size" has been added as a synonym of "--block-size". Ddrescue now terminates with an error if an unexpected EOF would discard any successfully read data, and automatically adjusts the logfile to shrinking input devices, like CD-ROMs written in TAO mode. A bug has been fixed which prevented status updating after the system clock had been put back. Control-C no longer overwrites status messages. Generate mode no longer requires the "--force" option. The new chapter "Using ddrescue safely" has been added to the manual.
