so if one dies you are out of luck?
Yeah, that is correct! It's just adding another point of possible failure (the only real upside is that you don't have to open up your TiVo and replace the internal drive thus, voiding your warranty). I think I might end up just selling mine. Also, if you remove the external drive permanently after you already installed it, you will end up losing all of your recordings.so if one dies you are out of luck?
