[Wolves] Data lost due to wrong partition file system while installing ubuntu

[Dan Dart]

I've had this problem much to my disappointment of Ubuntu not saying
in massive red letters "YOU'RE ABOUT TO FORMAT YOUR HOME PARTITION
WHICH HAS 200GB OF DATA!! REALLY??"

Personally, TestDisk failed at giving me anything.. PhotoRec brought
back bits of data it thought looked like certain file types (for
example I would get several hundred halves of mp3s), and not much
more. No structure, no names.
