Thank you for the reply. There were no jumpers on the drive at all and I noted there was also not one on the original drive I removed either. The cables are properly seated and the drive spins up when I have power to the tivo. I'm not sure if I need to do "intellipark" but from what I have read on here so far, it seems this drive, manufactured in March 2011, shouldn't need to have this done. I'm not sure what else to do.
