Im trying to fix an iPod for someone down the hall in my dorm. Its a 3g 15 gig. He has a Windows PC, and when he plugs it in, it would just flash the Do not diconnect logo and freeze up, I plugged it into my powermac and it does the same thing. When I unplug it, it still stays at that screen and I cant even reboot the iPod. Any ideas? Thanks
