One of my premieres is in a constant reboot cycle after receiving the spring 2012 update. I have been running it with a 1.5TB drive since I got it. I put the original drive (320GB) back in and forced an update and the premiere is working fine. Is there a way to fix the drive that keep rebooting while still keeping all the recorded shows and settings? Has anyone successfully re-imaged just the firmware partition from the original working drive? Any help is appreciated.
