I've had an HR10-250 since late '05 and have since added another. Within the last 4 months, I've added two HR20s to my account. When I added the last one last week, I deactivated my original HR10 because I've only got 3 tvs in the house. I'm thinking about selling it but I've got a big dilemma. My original hard drive has approximately 20 + hours of HD NFL playoff games that I don't want to lose. I've already archived them to DVD, but of course, I want to keep the original HD footage intact if I can. I have a spare 400 GB hard drive that I was using with 3.15e already on it. My question is if I sell the unit with the spare hard drive attached and keep the original hard drive with all my games, is there any way to get the footage from my original drive to work. From what I've heard, and I might be wrong, I can't just open up my 2nd Tivo, that I still have active and swap the hard drive. Correct? Are there any other options including hacking? I'd love to hear from the knowledgeable people here.
