On my Homebrewed Wii, my SD Card is not being read. It detects it is in there but Homebrew and anything else doesn't read it. My computer reads it fine. So I thought my Wii was getting old, so I decided to move everything to vWii on my Wii U, and it was working fine, for about 2 hours. Then I got the same error. Haven't tested on Wii U mode, but any ideas?
