Dear Maintainer,

Can you please forward upstream about this non interactive mode I did workaround this , using a hacked “expect script” I can share it (*), but I am fully happy with it…

So I'd like to put a resume task in my init script..

Recovering large disks could takes more than month …




I prefered to use ext4magic as :

  sudo ext4magic  /dev/sdc3 -r -f $USERl/Documents/ -d /tmp/local/tmp/

Note you have to resolv symlink by your own

I've just build a deb of latest upstream, feel free to merge latest patch at :;O=D

I built latest version of testdisk/photorec 6.13 there are no major changes in packaging

Feel free to have a look at and merge debian/watch in :;O=D

I can upload a version to mentors if needed

If you put it under collab maintenance,

I or others may be able to speed up integration

Problem while reading. Retrying from sector 24128


Had a 1TB (array) with broken HDD … ddrescue recovered all but 2GB last resort I put it in freezer and expect to recover a bit more
