I have a 3TB Roamio Pro (w/CableCard) and the drive is 90% full and is approaching 5 years of age. So. I want to copy all my shows onto a new drive before the current one fails. I read a lot of threads, but most of them dealt with using software to do the copy, but I want to know if I can use a typical stand-alone docking/offline duplicator to clone the hard drive? So, I have some questions: 1) It seems the recommended 3TB drive is the WD Red WD30EFRX which is 3.5" form-factor, is this the BEST recommended replacement for my 3TB Roamio Pro? Or should I get a different brand/model? 2) If my docking/duplicator device does sector-by-sector copies, can I simply insert my existing drive and the new drive into the duplicator and do a "Clone" and then place the new drive into the Roamio and it will work and have all my recordings? or do I need to do some post-clone procedures? 3) In one of the threads, it said I might loose "pairing" with a clone - is this "pairing" the cablecard pairing and I will need to contact my cable provider to re-pair my Tivo to the cable card (because the new drive caused the "Host ID" to change)? or will it loose pairing of the hard drive to the Tivo Motherboard? And if so, how do I repair the HD to the Motherboard? Any help will be greatly appreciated!
