text: memory stick all of a sudden stops working? the thing was working fine, now all of a sudden it won't...i can open documents on it, but can't fix something and save it, or save anything new...it's not full - not even half full...i've tried 2 different computers, and have restarted both, and have checked it for viruses....  any suggestions or ideas? if you can open documents on it, then make sure that everything on the stick is backed up and then format it.
