Hi, I just installed new 1 TB hard drives in both of my Series2 Tivos, and I think one of them is failing or has already failed. I can't believe it. Can anyone tell me if my suspicions are correct? The first thing I noticed was that while the first unit remained relatively quiet, the second unit started making a loud grinding noise. Like a really loud noise. A "I can hear it over a room full of electronic appliances" noise. I unplugged it to see if anything was loose, and after inspecting it and finding nothing loose, I plugged it back in, and now it isn't booting properly. It started bringing up the orange booting screen, but kept flashing back and forth to the channel the satellite receiver is on and the booting screen. It finally thought it had "booted" and is not flashing between the TV channel and the green "Tivo Central" screen, won't accept remote control commands, just keeps flashing between TV channel and green screen. Tried unplugging and rebooting again, same results. Am I correct about the problem?
