I just bought a refurbished Tivo Plus 1tb off of Ebay. I plan on upgrading the hard drive on it using a 3tb hard drive I removed from my current Roamio Pro (upgraded to 8tb). Is there anything special I need to do for this swap? Will the tivo just accept and format the new 3tb drive without having to use MSFR? I bought this for my girlfriend. I plan on setting it up at my place and then bringing it over to her place once I've got things started. We both have Spectrum, so I'm hoping it's just a matter of bringing it over and getting it set. Of course I would need her to get the cable card and tuning adapter. I was hoping I could do all the other channel/guide setup at my place saving time at hers. Speaking of cable card. The tivo I bought comes with a cable card. Would I be able to use that one and not get charged by Spectrum? Is there anything else I should keep in mind? Should I do a WD diagnostics on the old drive or blank it first? Thanks for any tips or advice!
