I think I've got a bum DirecTiVo here in our den. We hadn't used it in a couple of days, and turned it on just now and had a gray screen. Rebooted the unit and it came back, but had trouble aquiring the satellite signal. The blue animated menus are stuttering about once a second (jerky animated that puases then animates for a second, pauses, animates, etc.) I'm thinking it's a bum hard drive. Doesn't it sound like the symptoms of one? There's no extra fan or HD noise, but the jerky and slow menus makes me think a HD is the culprit.
It's got the original drive in there and an upgraded. How do I diagnose which of the pair is the bad one? If it is just one of the two hard drives, how easy would it be to swap it back to a 1 disk system temporarily until I can get a new HD for it?
