So yeah, I've been trying to format my HDD with the Wii U. And it just can't get formatted! The Wii U regocnizes the drive and I can click format but then it says that the drive couldn't be formatted. It's driving me mad. And no, the drive isn't corrupt. I can read and I can write on it on my PC. And I'm using an Y-cable and I tried different USB-ports. What's the problem?
