well my harddrive (western digital elements) is not working using a y usb cable in 2 usb ports BUT for some weird reason when i cover the 2 left pins with plastic of the power cable on the y cable wii u recognizes it and works.Problem is i think its underperfoming because wii u sometimes freezes when i play games from the harddrive and by freeze i dont mean the message that says drive disconnected but actual screen freeze
