I have a 1TB drive I am trying to use for on the WiiU but I get stuck at the checking drive phase when formatting. The drive was originally internal drive but its hooked up to a sata to usb 3.0 adapter which includes a power cord that plugs in. (just some background info not sure if this is the problem.) I searched around and couldn't find an answer. I read elsewhere that the wiiu only supports usb 2.0 (although I thought it would be backward compatible) Have other people got usb 3.0 working fine? I've also tried unblocking updates and seeing if the wiiu needed a connection to the nintendo network to format the drive but that did not make a difference. The wiiu also doesnt notice the drive on boot so I have to attempt this through the settings. I tried formatting the drive to exFAT and NTFS before hand and neither worked. Any help would be greatly appriciated. Thanks!
