Hello--I have a Series2 with a second drive added (TwinBreeze) on that was making a whining noise. I assumed that it was the fan, since we'd replaced that a while ago and it took care of the noise problem, so I ordered a couple of fans from WeaKnees last night. But this morning, the TiVo was making a horrendous grinding noise and the green light wouldn't go on! Is this the hard drive(s), then? Should I try plugging it in again? If it is a hard drive problem, is there any way to recover the data from married hard drives? I've been looking for what info I can find but I'm still confused about what should be my next step.

ETA: ok, I went ahead and plugged it back in. still not sure if it's a fan or hard drive problem or both. Any thoughts? Can I replace married drives with a single drive if that's the problem?
