I've already searched around for this problem, but I haven't had much luck finding a solution, so I'm hoping someone here can help me. I have a Series3 that used to randomly freeze and restart, which by all accounts seemed to indicate a bad hard drive. With the original drive, it would boot consistently though. After researching replacement drives on here, I settled on a 1 TB Western Digital AV-GP WD10EVDS. I'm aware of the issue with recent drives and the "Intellipark", but I followed the steps to disable that feature before installing the drive in my TiVo. And I used InstantCake to set the drive up for the Series3. However, the TiVo now behaves exactly as if there were no drive connected. It gets stuck at "Welcome! Powering Up..." screen, and all four front lights remain on, and the LCD shows the TiVo logo. I can never run the kickstart thing, because the lights never turn off, no matter how long I wait. Someone had suggesting pulling the battery out for an hour and putting it back in, I tried that, but it didn't appear to make any difference. I hope that someone here can help me out, because I'm completely stumped on this. Thanks for any help.
