I have been experiencing a very off problem with the wiiU and Sd cards. The console seems to believe the SD card is write protected, even when it isnt. I've tried with multiple SD cards, formatting the sd cards, everything really. But the wiiU just denies them. It can read data, but it cant write to the SD cards (which is vital for saving games or exporting data. Any help is greatly appreciated EDIT: Thank you very much Gamequest1! The problem was the wiiu's write protection detecting pin was bent out and thus didnt work.
