I have a HighDef tivo and had a WD external hard drive hooked up through ESata. Has worked great for over 3 years. Then a short time ago the tivo started getting stuck on "Welcome! Powering up..." screen. I researched these forums and the problem seemed to point to a hard drive problem after the initial steps of evaluation failed. My first thought was the tivo hard drive because I have had multiple tivo HD fail in the past. But before I went to gutting my tivo and replacing the internal hard drive, I tried uninstalling the external HD and poof. It would work. So naturally I blamed the external HD and bought a new one ... hooked it up ... and now same problem. Best thought I have now is to blame the ESata port on the tivo itself and I have no clue how to problem shoot that one. Any help would be appreciated.
