downloaded and installed update. When performing back up it stopped in the middle and said file full. Unplugged unit and when it turned back on I had to reinstall the software. When the my book logo shows on the screen it now has a circle wtih a
gauge that goes from green to red with the pointer in the red. It does perform a backup however when I run a diagnostic the quick smart and quick drive are good. The complete drive test stalls on 10% and then cancels. I have 1.7TB free. Should I erase the drive and start over?
