Now my wiiu don't read SD cards anymore. It happen when i was using CBHC, and i get the "-3" error that means the sd card can't be readed. Then i tested the sd card with MiiMaker (WiiU), and it says there is no sd card inserted, also tested with the vWii SD functions (SD Channels, Save Data Manager) and it says the sd card is no valid, but it appears inserted in the main menu. I tested multiple SD cards, all formated to FAT32, unlocked, always the same results. (SD card not valid) Possible solutions?, do a system format? or dismount the wiiu and see the sd slot?
