Can you please help with a replacement of the old harddrive in Roamio Pro? I am trying to update the existing hard drive with WD Red 3TB NAS (WD30EFX). Install was so easy, but once plugged her in and started the reboot, it froze on the Welcome Screen. Green Light but never the yellow light. Waited what seemed like half-hour and it never moved. I plugged the old drive back in and it started slowly but normally. Do I have the wrong drive? Am I doing something wrong? Any help would be appreciated. Thanks in advance.
