I'M BACK!! I scored a deal on a used Roamio Plus and 2 minis with lifetime. I have read a tutorial and upgrading the drive seems straightforward, especially for a computer repair tech like me. Just plop it in and the tivo will handle the rest. But I still have questions. How does that work? Is the system on a built in SSD? The WD Red drives seem to be popular here but the Purple seems more appropriate to me with lower power consumption and a purpose of a surveillance DVR. Can I get any more info on this? I currently have a Tivo HD with a 1TB drive with lots of stuff on it. I'd like to transfer all of that. I think the Tivo site used to have some transfer ability but not sure how my ancient (but still great) HD works into that. Last time, I just copied from one to the other through the Tivo menu, one at a time. Any info on that would be appreciated as well. I intend to use MOCA. Do I need to install some kind of filter on my cable line to avoid making my entire neighborhood a MOCA network?
