I have been using an mp3 player 4Gb as a flash drive recently for doing a Windows install from a USB. It is generic / very cheap. It was working fine until I recently formatted it (FAT). Now when I connect to the computer it (I think) mounts and dismounts quickly before I can even see it. (I hear a beep, and sometimes it shows up in "Computer" area before it disappears.) How would/could I go about trying to fix this? Thanks!!
