I am pleased to announce the release of GNU ddrescue 1.19.

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.

The homepage is at

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

The sha1sum is:
5c5bfa4e2d0cb98feb1fd66cb9ea0c8ab2c7d34d  ddrescue-1.19.tar.lz

If you are wondering why ddrescue is distributed in lzip format, you should read this benchmark

This release is also GPG signed. You can download the signature by appending ".sig" to the URL.

Changes in version 1.19:

  * A race condition at start of run with "--timeout=0" has been fixed.

* The new option "-P, --data-preview", which makes ddrescue show a few lines of the latest data read, has been added.

* The new option "-u, --unidirectional", which runs all passes in the same direction (forwards or backwards), has been added.

* The new option "-X, --exit-on-error", which makes ddrescue exit after the first read error is encountered during the copying phase, has been added.

* The new option "--ask", which asks for confirmation before starting the copy, has been added.

* The new option "--cpass", which selects what passes to run during the copying phase, has been added.

* The new option "--pause", which inserts a pause between passes, has been added.

  * The option "-l, --logfile-size" is no more needed and has been removed.

  * Ddrescue now skips on the first error during the copying phase.

  * Trimming is now done in one pass and may be run in reverse.

* The splitting phase has been replaced by a "scraping" phase that scrapes together the data not recovered by the copying or trimming phases. Scraping reads each non-scraped block forwards, one sector at a time.

  * The long name of option "-n" has been changed to "--no-scrape".

* During the retrying phase the direction is now reversed after each pass. Use "--unidirectional" to override.

* Model and serial number of ATA devices are shown with "--ask" or "-vv" on GNU/Linux.

* The configure script now accepts the option "--enable-linux" to enable the compilation of linux-specific code.

  * The license has been changed to GPL version 2 or later.
