I'm thinking about uograding the internal hard drive in my Roamio Basic. Is it really just as simple as popping the case, removing the old drive, and inserting the new one? I upgraded the drive in my Premiere, and done various computer uogrades, so stuff like this isn't a problem, but I don't currently have a computer, just my smartphone (Obviously I couldn't upgrade a Premiere lol), so if it does require a computer, I'm out of luck. If that's all that's required (I realize I'm going to start from scratch regarding settings, season passes, recordings, everything), what model hard drives are recommended? I see Red NAS drives from Western Digital that aren't much more than regular drives. Are those worth it? And how many hours of recording time (About) would I get for 1TB? 2 TBs? Keep in mind I'm recording OTA?
