G-Drive Model # 0G00203 white light flashing

When I plug in the drive to power adaptor the white light flashes and the drive does not seem to be spinning or powering up. Do I have an adapter problem? I actually have 2 of these drives and when I plug in the other drive with the same cord it powers right up. It worries me that the DC in port is malfunctioning. I want to purchase a new power adapter but I can’t find a part number or adapter specs. Any help is greatly appreciated.

The specs are 12v 2a. Part # 0G01008
