I just used dd_rescue per the instructions listed in Post #3 with a Knoppix cd. I have a series 1 Sony svr-2000 unit that was previously upgraded to 80GB AND 120GB drives. I used dd_rescue on both drives and copied the old drives to the new drives. The new drives are both 160GB drives. Everything went fine during the copy process with no errors (surprised me) on either drive. I put the new drives in the Tivo and the Tivo doesn't get past the first "Your Tivo is powering up" screen. I put the old drives in and everything is fine. It's pretty apparent that the data wasn't successfully transferred to the new drives. Does anyone have any ideas of what might be wrong? I've checked the jumpers and even reversed the MAster & Slave to make sure I didn't get the drives mixed up. Also, on another note, I've read that I can't install the drives from my Tivo into another identical Tivo due to the Serial Number of the hardware not matching the serial number stored on the Drive. Is this true for all Tivo's such as the series 1 svr-2000 or only specific to certain Tivo models such as series 2 or other brands. I'd really like to have a complete backup (hardware and software) of my Tivo setup because I have about 100 hours of saved programs. Thanks for any help.
