  • Is the USB drive a drive that has a write-protection switch on it, or no? If the answer is no, then I would surmise the USB drive is broken and nonfunctional, because it likely can't be properly read/written to and is causing errors. – Thomas Ward Jan 19 '23 at 18:34

I agree with @ThomasWard -- with the cost of thumb drives today, it's not worth spending much time on it. If there was sensitive data on the drive, you might want to get a hammer or similar and physically destroy the drive (including the Flash RAM package on the circuit board inside) to ensure it can't be read, as well as not being able to be written, but otherwise, it's not worth your time to try to deal with it.
