A few times a week my Tivo HD will spontaneously reboot. It's been upgraded to a 2TB internal drive and sits behind a power conditioner. None of my other equipment shows signs of any power surge or disconnect. From what I've read, it might be a HDD problem or a power supply/cable capacitor issue. I actually have an old HD that I tried to repair with a new power supply when it would hang forever at the "Just a few minutes more" screen. So I will probably try to examine the power supply/cable and replace if there's any question about them. Seems a lot easier/quicker than copying the content of my current drive onto a new drive. Anything I should check or other ideas as to a cause?
