I am pleased to announce the release of GNU ddrescue 1.24 'Catalonia'.

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.

GNU 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

The sources can be downloaded from or from your favorite GNU mirror.

This release is also GPG signed. You can download the signature by appending '.sig' to the URL. If the 'gpg --verify' command fails because you don't have the required public key, then run this command to import it:

  gpg --keyserver --recv-keys 8FE99503132D7742

Key fingerprint = 1D41 C14B 272A 2219 A739  FA4F 8FE9 9503 132D 7742

Changes in version 1.24:

* The new option '--command-mode' has been added. It activates a scripting interface similar to the one of ed which reads commands from the standard input and executes them, copying parts of the input file on demand.

* Ddrescue now tries to create a backup copy of the mapfile, with the name <mapfile>.bak, every time it is going to overwrite a fsynced mapfile. On startup, ddrescue verifies that the backup mapfile (if it exists) is not a non-regular file, and that its name is not the same as infile or outfile.

* It has been documented that when ddrescue finishes, the contents of any areas marked as bad-sector remain untouched in the output file.

* The configure script now accepts appending options to CXXFLAGS using the syntax 'CXXFLAGS+=OPTIONS'.
