I own 3 TCD652160 HD TIVOs. I just upgraded one TIVO hard drive from 160GB to 1TB, everything went great. All my TIVOs have a Tuning Adapter, and Cable Card. The old hard drive has quite a few movies on it that I would like to watch. I put the old drive in a different TIVO. I get a hardware error. I have tried everything. I have been told: Old drive is tied to Tuning Adapter. Old drive is tied to Cable Card. I disconnected the Tuning Adapter and Cable Card, leaving the strip down TIVO. I ran Repeated Guided Setup, and Restart TIVO. I still get a hardware error. I am new to TIVO upgrading, etc and I really need help. Please advise.
