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 …

DDRECUE

EXT2/EXT3/EXT4

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
