Well, I have a 30gb ipod video that all the sudden won't connect to a computer. I've tried different computers, pc, mac, and different usb wires, but it won't mount, or be recognized by any computer. It will charge if I put it into a speaker system, but won't truly turn off. When I turn it off, it dims, and says "charged". In addition I've tried the standard reset, but it doesn't help. It works to play music etc, but I have no clue how to fix it. I can't add, delete or do anything. help!
