OK, update… turns out that I probably got about 75% of the pics back.
Still looking for the rest. They just don’t appear anywhere (split drive into 2 partitions, quick formatted one of them). Restorer keeps crashing when I run it for a short while and I have to start the process again so this is proving most difficult!
I’m also trying out GetDataBack which locates plenty of files but is having serious problems retrieving them as they appear corrupt. Any tips?
I wouldn’t mind getting the pictures back and actually being able to USE this HDD!
