Has anyone upgraded their Roamio and had it fail? I've formatted two disks (one 500gb, one 1TB) and still my Roamio doesn't want to play nice with them. Both are Seagate. I pulled the old drive, put the new one in, and booted up. I get to the "Welcome, Starting up!" then the lights on the front act like they've had too much caffeine, blinking like crazy - all four of them. I've tried formatting as MBR and also as GPT and with a partition and without, but still I get nothing.
