Advertisements I want to expand my recoring capacity "a bit" and am planning to replace the standard drive with a 1tb drive to my Tivo HD. (I want to replace the drive now so I can expand the capacity again latter on if I want and not have to lose my recordings at that point) I can not seem to settle on which drive to get. I am leaning towards the Hitachi DeskStar HDS721010KLA330. I was looking at the WD GP line but from what I can tell there are several different drives in that line that I may end up with and some of them may not work. Any advice?
