So it happened (before I had time to set up UStealth), my daughter formated my HDD for Wii mode. Good that I have the data all on a backup HDD. Now I want to reformat the HDD on Windows, but the HDD isn't shown in the Windows explorer. I here the sound that hardware is found, but the drive doesn't show up. Is this normal because the Wii U formated the HDD? How can I format it again?
