I have a TiVo HD with an external WD DVR expander (wd10000f032). Today I turned on my TV and saw the orange "Welcome! Powering up..." screen, and it wouldn't get past that screen. Restarted several times, tried to get kickstart going, no joy. I disconnected the expander and restarted, and this time I got past "Welcome! Powering up..." and the next screen ("Almost there...") before getting the screen asking me to confirm that I wanted to remove my external drive and lose my recordings.
What I want is a) to confirm my conclusion that this means my issue is a failing WD expander and not the internal drive, and b) to see if there is some way to recover the expander - the whole drive if possible (maybe some diagnostic tool that fixes the drive or marks the bad sectors as off limits or something), but at least the recordings on it.
More info - when the expander starts up the circles glow orange like normal, but I hear a noise that it repeats three or four times. The pattern is a buzzing for about a second, followed by a quick buzz at a higher pitch (makes me think the drive arm/head/whatever moves from one side to the other at one speed, then goes back at a faster speed - it sounds like a stepper motor). Like I said, it does this three or four times when the drive starts. When I restarted the TiVo with the drive plugged in, it also repeated the pattern of buzzes after the "Welcome..." screen appeared.
