I posted in this in the Help forum before I remembered about this one so please forgive the duplicate post. I just upgraded my dad's stock drive in his Tivo HD to a 2TB WD Green drive. I used winmfs to copy the stock drive to the new drive which worked fine. However, the Tivo is only showing available capacity of 21 HD hours (the capacity of the stock drive). It was suggested that I missed the Supersize command in winmfs but I'm pretty sure I did that and I don't see how that would result in only seeing the drive as a 160 GB drive rather than a 2TB drive. Any ideas?
