My symptoms are extremely frequent pixelation, stuttering of the playback, and once in a while, it refuses to record a show, or entire sections of the show are missing. I assume I'm correct in my thinking that this means my hard drive is failing. It just so happens I have a spare 80Gig hard drive hanging around in my house that I'm not really using. (It actually was inside a broken computer than I just replaced. I've temporarily installed it as a slave in another working computer, and I intend to get all my important data off it. Once that's done, I have no objection to harvesting it to install into my HDR212) Do I just follow the Hinsdale instructions of upgrading? Because this isnt' really an upgrade; it's a repair. Is there a better instruction document I should be reading to replace, instead of upgrade my space? Also, in my case, the previous owner of my HDR212 already did an HD upgrade. It's capacity is currently 194 hours, so I'm guessing this might mean it has two drives in it, instead of the original single drive, so I'm guessing this could complicate my repair if I'm going back to one drive. (I don't mind the space reduction, as I really only intend to use this TiVo for programming conflicts.) Or is it possible that only one drive is bad? Do the instructions have info in them to help me diagnose if both drives are bad, or if only one is? Because if only one is, maybe I'll keep my extra drive for my computers, and simply remove the bad drive. But if that is the route I go, I assume I'll need to tell the TiVo (somehow) that it only has one drive now. BTW, I don't care if I lose all my settings and programs on that TiVo. Also, one more bit of info: it's unsubscribed, if that makes any difference to how I go about fixing it.
