Advertisements Hi, using mfstools 3.2 I mfscopied -ai original 500gb hdd to wd red 2tb for my TCD846500 Roamio HD. Kickstarting 57 causes continuous 3 screen cycle between starting up, almost there, green screen, with roughly 10 seconds at each screen. I mfscopied -ai the original 500gb hdd to a wd blue 1tb and that worked successfully. I then erased the wd red 2tb and installed it in the tivo. Tivo accepted the drive, did a fresh start setup procedure and the clean drive works fine. Does anyone have any ideas as to why 500->2tb is failing for me?
