I've been trying these and other solutions for 2 days now. One minute the flash drive was fine, literally the next, it was unreadable. I have a lot of valuable files on this stupid flash drive. Every piece of freeware finds files & sectors but can't recover files. Is my only option to take it to a professional? And how does that happen, a drive converting itself to RAW? I've tried reformatting the disk, but Windows stops half way.
