Solved the issue!
model SRD00F1
The drive is a 500 gig usb 3.0 powered Seagate black drive with a very odd connector, so I had no way to connect a Y cable to it, However by connecting the drive to a powered usb hub and then connecting the hub to the wii u's back via a Y cable I circumvented the problem :3 drive now gets enough power to work properly ^^
