It occured to me as I was about to hook-up a USB HD to my LS120 that I

could perhaps swap out the internal HD for a larger one.  I understand

that I would have to perform an image of the existing HD but I can't

imagine that would be very difficult since I've done something similar

to my first gen. Tivo.  Can this be done and if so is there some kind

of a guide available for this procedure?  Thanks.
