I would never trust a flash drive that is already corrupted. You can buy any USB flash drive now, even at the grocery store. Throw that one away so nothing else gets corrupted. They don't last forever. It's good to keep one you are using, and another one you just keep updating, as they don't last very long. They just aren't as dependable as we would like to think they are. I got one at the embroidery store that looks like a tomato pin cushion for $18. It looks really cute dangling from the chain with the little strawberry hanging there.
