Hi there,

I have not tried this, as far as i know the software does support ext partitions, however I am not able to confirm if it is possible to do from SSH, Lets see if another user can share some information or tips on this matter.

I had no problem connecting to my ssh . but impossible to install TestDisk with the command line apt-get install testdisk
then totally lost …
