I had this memory stick for a while, and its been working fine. It has a lot of my important college work on it too. Just a few days ago it randomly stopped working. I've tried it on all computers I can and none of them recognised it, and it didn't pop up in 'My Computer'. The best reaction I got was on this laptop, where it said it was processing, but then said that I did not have a suitable driver software or something like that. Please help, I have a lot of work on it .
