Hi All, I've done many transfers and HDD updates in my older Tivos, but I'm a bit stuck on the best way to upgrade my existing 3TB internal drive to a 6TB drive, while keeping my recordings. I've successfully cloned the drive and tried running `mfstool add` but the command fails. If I run MFSR it will reformat the 6TB drive (which is ok, if there is a known way to re-copy data from the original afterward). Has anyone nailed down this process? I can't seem to find this combination; new 6TB drive and keeping old recordings (all on a single drive). Thank you!
