Advertisements Can someone please help! I thought I would be clever and upgrade the hard drive in my series 4. when I cloned the drive it was still reporting a 500GB so I put both attached both drive to my computer and opened them with Windows disk management! Okay now I know I should not have done that! I bought another Tivo TCD746500 but the image from that drive would not work. So i bought another Tivo TCD746350. This image sort of worked until I tired to erase and reset. Now I'm stuck in the guided setup loop. I think I need a virgin image so I can start over! Help please!
