I lately updated my flash drive with new songs but I opened it so I can play them and it said I had to format it. I got worried because I have important stuff on it and I didnt want to remove it. Its a Kingston 2GB and when I checked the space it said , 0 bytes used and 0 bytes left. My Kingston was named but when I checked it was called Removable Drive. My computer is a Vista and I have tried working it on other computers but it wouldn't work.

Help
