Hi Andrew! You're right. The problem I had with Testdisk was that it could not find any partitions on the image or on the actual usb stick. My bad :) I was looking forward to examining the thousands of files that Foremost recovered, but after what you say it wouldn't matter much. I assume the files recovered are fragmented and will try to see if I can find a tool to help me defragment them (if that at all is possible).
