I'm definitely reading, but not necessarily comprehending. I upgraded a 60GB TiVo to 2x80GB in about 2002 using 2.4 and some userland tools. in fact i was just contemplating doing another upgrade since the 80s in it now are on their way out i think, so i'll even have some spare TiVo drives to fool around with during the development of this thing. I'm probably not qualified to begin an undertaking like this, I'm just a student, but....I've always wanted to be a kernel hacker. ;-) but i'm not sure I understand what would be involved. And, does this mean I'll have to use 2.4 to do my next upcoming drive replacement? (replacing the drives in the tivo requires a host linux box on which to do it) If someone would be kind enough to give me a little more info about the dm driver for tivo drives, i'd at least entertain the idea... -Aubin
