My HDD isnt recognized by the wii-u. Its a 2.5 250gb WD Scorpio Black inside a non powered usb 3.0 enclosure. I tried all the ports. I tried using with a Y-adapter and without. I tried NTSC and Fat32 formats. The light comes on the drive but nothing happens in the wii-u menu. The drive also works fine on my PC. Could the wii-u be formatting it without any notification?
