So, I ruined my old 4GB memory stick recently, and rendered it unusable, is there anything I can do to fix it? My PSP runs 6.60 PRO-C2, and I was in the middle of trying to copy Misadventures of Tron Bonne to my PSP from my unmodded PS3 while in a hurry, and the PS3 was going really slow that day (Took about three minutes to copy the 8KB save file), and I ended up having to yank the PSP mid-copy. As I expected, it created a corrupted file, but my PSP could not delete it. Later connected it to my computer, tried deleting it through Windows, Windows said it deleted without error, but it still remained in the folder. Tried deleting the entire GAMES folder, nothing deleted. I tried formatting the entire memory stick, the PSP couldn't do it, Windows said it did it, but it didn't actually delete ANYTHING from the stick. Would putting a magnet to the memory stick and trying to format it work? If not, any other solutions?
