Dave, I have a Samsung YP-910GS hard drive mp3 player and it reciently stopped working. I tried to reload the firmware but when I connect it with USB the computer says unreckonized USB device. I know the hard drive is a 1.8″ Toshiba, same as in the iPods, but it says the drive is an ATA drive? Is there a way I can check the disks for errors and repair it, if it is corrupted?
