I have a TiVo premiere I've owned for about a year and half then the hard drive died. TiVo was stuck at powering up and I confirm the drive was dead with the WD diag util. I bought a new WD 2TB DVR drive from Amazon to replace the dead drive. I download the current MFS software but I noticed there is no software image for the premieres, I own another premiere and I copied that hard drive to the new 2TB drive, expanded it and I put the new drive in the TiVo that had the bad hard drive. I boot TiVo now with a 2TB drive up and first I get a M51 error. The error suggests I reboot to fix the problem which I did and it reboots fine, video works I can see old shows that have been recorded but when I go in the system info screen the TSN shows up as all 0's and it will no longer record shows. The software version is the latest version 20. I assuming I can't just copy the hard drive from another TiVo like you could with older hardware. I've do a lot of searches and I find plenty of docs on upgrading to a new hard drive using an already working original drive. Anyone have any suggestions? Is my other option to buy a drive that already has a software image on it?
