My My Book 3.0 2 TB won't start up. I thought is was the USB, so I asked for a replacement but it still doesn't work. It powers up only if i press the power button in the back. Plugging it into my computer doesn't turn it on at all. Somtimes the light on the front blinks, sometimes it doesn't. Is there any way to salvage the drive or should I just RMA it?
