The power connection on the back of my MBWE (1TB) WDHINC10000 accidentally came unplugged and I lost power. I plugged it back in and held down the power button but it will not power up. I tried unplugging and connecting to another outlet and still will not light up. I am holding down the power button waiting for the led on the front to turn on but it does not, even after a whole minute. Any help is appreciated.
