I believe my Tivo's hard drive has died, after power-up (plugging in the AC cable), I get the Welcome - Power-up on the TV, the hard drive drive-spins, sounds like there's a marble running around inside, and then the Tivo resets to Welcome - Power-up on the TV, it does this approx 3 times, and then nothing. When I plug in my Tivo now, I get nothing, is the "Welcome Power-Up" read from the hard drive? Is it safe to assume the hard drive is dead, I checked all the cables, and tested the voltages on the power supply, and all the voltages appear to be there. The tivo hard drive light flashes, but doesn't spin-up, which makes me believe it's dead, if I use another hard drive (not tivo configured), this drives spins up. Tivo Green Status LED and FAN always start-up. This is an original Tivo not modded, purchased when they first arrived in the UK in Sept/Oct (long time ago). I don't know what Tivo version is on it 2.5.5 or 2.5.5a. Is they any point in installing in a PC and running Maxtor tools?
