Trying to recover my data I already tried photorec but wasn't successful.
I used ddrescue to copy all data from the 'original' disk (/dev/sdb)

More info:

I ended up with about 40 .cow files ranging in size between a few KB and 1.7TB, none was usable.
qemu-img info and check even didn't complain about any errors with a few files. Still no t-shirt.

Will give testdisk another try.

I don`t want to be overly verbose but it might help someone else.
This is what is happening right now.

Will try with a new copy. Right now ddrescue is still running. Maybe without using testdisk at all.

Good day,

it has been asked before. But I don't get the answer.
I need to recover qcow2 files that hold my VMs created with qemu-img. Photorec (tested different versions) does find *.cow files but many more than I originally had and of very small size. The ones I am looking for are about 80GB.
