My HDD works fine, however i'm having issues with USB loader not initialising. Also, if I want to put emulators/roms on the hdd I can't because the drive doesn't appear on my PC and then the Wii U just wants to reformat it.
What is the drive formatted as?
That's your issue, you can't use a Wii U formatted drive for USB Loader, your hard drive needs to be in FAT32 for USB Loader to see itI don't know, just whatever the Wii U formats it to.
