I'm a GCSE student in the UK (obviously) and today my USB suddenly stopped working. I get a message saying that it can't recognise my USB. It's a 4gb Memory 2 Go. I've tested it on 4 computers. 3 Windows XP (SP3 Home & Pro), 1 Windows 7 (Home prem.). I didn't work on any of them.
I had so much work on it, most of it's due in within 2-3 weeks.
I would greatly appreciate any help on this problem.
