In what I now regard as an act of lunacy, I tried to upgrade the hard drive in my standalone Series 2 (TCD540040) to a 160 GB Seagate drive. I've actually tried a myriad of things to get it working, including (in order): Copying the original drive to the new drive using the following methods: "Hinsdale guide" with MFSTools CD (which, from a little forum searching, I now realize is out-of-date) MFSLive CD (version 1.3) Weaknees boot disk dd_rescue (from a Knoppix disk) Checking the drive jumpers Replacing the IDE cable Each time, when I install the new drive and power up the TiVo, I'm greeted with an endless loop of "Welcome! Powering up...", followed by a reboot (and, of course, wailing and gnashing of teeth by yours truly). As if that wasn't bad enough, I tried putting the original hard drive back...wanna guess what happened? Yep...another reboot loop... Has my poor ol' TiVo seen its last "Judge Judy" rerun, or can some of you nice folks help me bring it back to the land of the living (or at least booting)? Some additional information: After each copy attempt (except for the dd_rescue attempt), when I ran mfsinfo on the upgraded drive, I got a total of 6 partitions, the first 4 of which matched the original drive. The fifth partition showed a size of zero, and the sixth appeared to contain the remaining drive space. (For what it's worth, the dd_rescue attempt yielded identical results from mfsinfo using the old and new drives.) I really do appreciate any assistance any of you can offer, and please let me know if I've accidentally omitted any useful details.
