I have a SDHC Kingston 8GB Class 4, it used to owrk in my Wii but no longer does! I put it in my Wii and the SD Icon is grayed out! It works fine in my PC but not in my Wii, it used to but now it only works in my PC! I used to need an SDHC Card Reader for my SDHC Card but now it works in my SD Card port, I think this is due to a format problem :/ I put it in my Nintendo Wii and it wont read, even when there's nothing on it! I therefore reformatted my card and it still doesn't seem to have any affect, I formatted it to FAT32 so I don't know what the problem is! Can someone please help me, I don't think it's a problem with the SDHC Card, it still works fine in the PC!
