I copied all the information (vc ww) from my 2gb over to my 4gb sd card. Now the wii menu is saying that my 4gb device cannot be used. How come? What do i do for the wii to read it? I'm on a 4.0 ntsc wii. Update: So i just put in an ordinary 512 mb sd card and that gets the same error so its no just sdhc specific. It's weird how my 2gb is the only memory card that works.
