I bought an SD card the other day, put it in my Wii and copied my VC games to it with no problem. Today I put some mp3's on the SD card, put it back in the Wii and now the Wii won't read or Write data to the card. If I put the card in my PC's carf reader it shows the Wii files and the mp3 files. When I put it back in the Wii and go to data management and then to SD card it knows there is a card in the slot as it tells me how many block there is. But it shows no data and when I try to copy VC game files it says this file cannot be copied. Any clues?
