I just purchased a WD 2Tb HDD on Ebay with a Tivo image for a TCD648250B Series 3 HD Tivo. It's supposed to be plug & Play for my Series 3 Tivo. Since I have four of these TCD648250B Tivo's, is it possible to clone this drive for use in my other Tivo's using blank 2Tb WD Drives? If so, what software do I have to use, or can I simply use a stand alone hard drive cloner? Thanks!
