So I'm trying to use an HDD for game backups on my Wii U - it's a UnionSine 250GB USB 3.0 Drive. But no matter how hard I try, the Wii U doesn't detect it. I've tried formatting it to Fat32, tried turning off sleep mode, but it just doesn't work. But not ALL USB devices not work on my console. My USB stick works, somehow, so I think it has something to do with the drive itself. Any help is greatly appreciated.
