Dont no if anyone can help. I have a 4gig memory stick (well did have) that when i plug it in, all it says in properties is that the size of the memory is 0 bytes, used 0 bytes, free 0 bytes. I've tried to format it, but i get a message to insert disk I really haven't got a clue whats going on. Im running XP home, it worked fine for about two weeks, then this. Any advice would be great.
