I just had my RIO installed into my car, and it worked fine for a while, but then started giving me the "No Hard Disks Found" error. I have already replaced the cable before, so I brought the RIO inside, checked the cables, and tried starting the RIO back up again. It won't power on at all. No hard drive spinning, no LED, nothing. I tried it in my car, as well as connected to an external power supply. Does anyone have any thoughts?
