Forgot to fill you in. I was in the airport and the usb was in the bag. Could the x rays have damaged it? It doesnt even show up in My Computer, you can open it in auto run tho. So could that ^ have erased everything?
There are plenty of free programs to recover files from memory sticks. Only reformat it after you have recovered everything you can. I've used rescue pro but i dont recall if I downloaded it or if it came with my drive.
