So, I just modded my vWii, and everything is working fine, but I can't make any usb loader recognize my HDD. It works fine on my regular Wii, but I can't get it to work on the Wii U... I've tried every USB port to no avail. Do I need to change its format? It's currently formated as NTFS, but since I'm only using it for game storage there should be no problems right?
