I have a Roamio Pro running TE3, a little over 5 years old. I bought it from TiVo with factory 3TB green drive, which has always been enough storage space for me. I was thinking about replacing the drive soon with another 3TB, and holding on to the original as a backup. I will probably get the recommended WD Red. I've read different opinions whether I will loose my cable card pairing. I really don't want to loose the pairing. I don't care about loosing my recorded shows and such, just not the pairing. Can I just pop it in, or do I need to use MFS Tools 3.2?
