I've got a TivoHD. I still have the original hard drive somewhere, but it's been upgraded to a 1 TB hard drive. However, now I want to "downgrade" to my Seagate 750 GB hybrid drive (it's quieter, etc.) I don't care about losing any saved data (meaning stored DVR'd shows). Can I use WinMFS tools to copy the existing 1 TB "system" stuff to the smaller drive? If not, I'm assuming I could use the old, original drive, copy and re-expand, although it'll need a bunch of updates after that and possibly a re-pairing of the cable card (I don't remember which cable card was in what device at the time) since Time Warner pairs everything to the specific Tivo, unlike Verizon.
