I've used TestDisk before but now I'm lost. My father-in-law accidentally changed his usb RAID1 case's mode. Nothing was formatted but the drive(s) appear empty in the drive manager.

In two other programs it seems to be all there, but other than copy things to a new drive, they don't seem to be able to restore the drive/partition:


In testdisk, I can press P but it'll show a rather empty drive with one folder and subfolder. I can't figure out what to do to restore the partition.


I would be thankful for any advice!
