I bought a 16gb usb flash drive for all my music. When I put it all on there, some of it seems to become missing! Everything is organized in their on folder, but some of the folders end up with the same contents as other folders, but the duplicates seem to be corrupted! I have formatted it over and over! I tried changing file types and everything! I just don't get it, the capacity is there! Am I doing something wrong? I bought ANOTHER 16gb drive and it does the same thing, and is unreadable in my car stereo! PLEASE HELP ME!!!
