Just installed mybook and computer won't run

Just got a new MY Book 3tb.

Started a backup and now the computer won’t respond to any key strokes but MyBook is flashinf like it is doing something. How do I safely remove the new drive without damaging it? I just had another drive go bad because my son unplugged it while it was saving other data on my other computer. Any sure help is appreciated.


If the computer is frozen, you can manually press the power button and then disconnect the My Book.
