Formatting is data destructive. Don't do it.
Have you tried any data recovery software?
That said, the fact that formatting failed would suggest that your drive may have a physical problem, unless it has a write protect switch.
Thank you for responding.
No, I haven't tried any data recovery software. I'm not even sure where to begin.
Sadly, I did try formatting, so this may be a lost cause. Today, I plugged a different flash drive and it asked to be reformatted, but I didn't do anything, and it came out fine. Why is it suddenly asking about reformatting? This is new, what could I have done? Please help.
