Advertisements I have a TiVo Premiere TCD746320 that would no longer boot up (all LEDs blinking on the front) so I tried copying the drive to a spare server SATA drive I had laying around (500GB Hitachi 7200RPM). While the copy worked, and the TiVo now boots up with the replacement drive(yay!), I get video corruption/blocky quality while watching live TV. The replacement drive is pretty old. Do I need to get a brand new Western Digital drive(like maybe a Purple?) or is there something else going on with my TiVo?
