So, I've taken a few days break from trying(/failing) to upgrade my internal drive, thinking I'd gotten a bum WD10EARS from Newegg. Was watching the Olympics yesterday and noticed that my TiVo started to freeze a little bit. The playback would stop, occasionally the DVR functionality would lag. Generally, I'd rewind, go forward, and it'd stop at the same point, but if I changed channels and went back, everything was fine. Now I'm starting to wonder if maybe the new drive is fine, but the current (stock) drive has a bed sector (or similar). Has anyone heard of this happening (whether it's the symptom or the cause) ? It would go a long way to determining why WinMFS won't finish copying my current drive to the new drive. I'm thinking of running the WD LifeGuard utility on the new drive and making sure it's a-ok (takes ~96 hours!), and if it is, just accepting the fact that I will lose all my recordings, and that I can always swap drives if I need to. Anyone have another thought, or agree with that? Similarly, I have an old Series 2 lying around, that doesn't have service. Can I put my current TiVo HD drive into the Series 2 and use that to watch the rest of the recordings I have on there, until I don't need the old drive anymore? Or will TiVo balk at that? Thanks everyone!
