What happens, exactly, when a Tivo is "Pending Restart"? Clearly, a new version of Tivo software has been downloaded. I understand this download goes to the OS partition that is not currently active. I believe the Master Boot Record (or equivalent) is then set to boot from the alternate partition. Is that all there is? Or do files get unpacked from some hidden compressed source during the boot?
OK, the reason I am asking is related to my current problem. I have a 1 TB drive that constantly reboots after 5 months of working fine. When I copied this drive to a new 1 TB drive, the reboots copied as well. Corrupt OS file(s), perhaps? So I copied my original drive to the new 1 TB drive, fixing the reboot issue, but losing all recordings. I now wonder if I can use MFSTools to copy the contents of the alternate partitions onto the other 1 TB drive, switch the boot record, and effectively have a fresh OS with my existing recordings.
Does anybody understand the OS upgrade process well enough to give some guidance on this?
