Advertisements So this morning at 4am my wife wakes and can't sleep. She turns on the 160hr tivo to find it skipping/ freezing. I tell her to reset it and now we're caught in the almost there loop. HD is fried. I'm trying to decide if I should get a upgrade drive or replace the box. Here's my thinking: I'm not sure if I'm capable of replacing an unformatted drive, so I'd probably have to get an upgrade kit. Looking at one of the sites, that replacement kit costs more than a new 80hr DT tivo from costco. Long story short: how hard is it to do the "instant cake" thing? or should I just get a new tivo.
