My TivoHD ate it's original disk drive a couple years ago. I used one of the recommended drives and a program referenced in these forums to rebuild it and everything was fine until a month ago. It began with the picture sometimes freezing if left on the same channel overnight. A quick channel change would bring everything back to normal. It was random and rare so I thought little about it. A week ago, it began pausing for a fraction of a second during playback but not, I think, live TV. That raised alarm bells, but I didn't have time to deal with it. Yesterday, I watched some live TV and a few pre-recorded shows then went to bed. This morning I noticed the picture was frozen again. This time, the channel wouldn't change, the Tivo button did nothing. It was COMPLETELY frozen. I pulled the plug, waited 30 seconds, and plugged back in. All I get is "Welcome! Powering up..." and nothing more. Green power light is on, but nothing else. Is this another drive failure or am I looking at a bad motherboard? I can replace the drive again if that will work, but don't want to go to that trouble and expense if it won't help. Suggestions? Also, if the existing drive won't boot but the data is otherwise undamaged, can it be retrieve onto a new drive? If so, could someone point me to the instructions for that? Thanks.
