Earlier today I loaded up a new 32GB microSDHC into a USB adapter to see if the WiiU would recognize it as a storage option (since I got the measely 8GB) and it did, so I moved over everything from my system onto the microSD. I also got Sonic & All Stars Racing Transformed in the mail today, so I loaded that up, installed the updates, then shut down the system so I could play later.
When I came back later and tried to play, the system froze up and gave me this error code saying either the internal or USB storage had failed, and to contact support. I rebooted the system and went into settings to see if I could move anything from the USB storage, but it froze up every time I tried. There's nothing on support for this error code, just my luck.
Is there anything I can do? Everything from my new system is on that microSDHC, and it wouldn't make me a very happy person if it was all lost because the microSD decided to let me move everything to it and then fail on a whim.
