Perhaps this belongs in one of the TestDisk forum branches. If so, I can create a new thread there.
I did get beyond the 'stuck at 25% problem' but find that many files I'd hoped to find were not found.
I finally managed to make time to run an overnight deep search with the partition type set at Intel. I saved Snips of most of the screens I encountered, but I could not understand how to check for missing files and eventually 'Quit' my way out of the program. I cannot make sense of the log file, so I will paste it below. Does it suggest that this is possible?
thanks,
baumgrenze
