I've been using this same MicroSD card with my CycloDS for about year with no problems, but yesterday when I turned on my DS it gave me a message saying something to the effect of the MicroSD not being formatted with FAT16 or FAT32. Even though I don't want to, I'm willing to reformat the card. However, my computer doesn't recognize the card when I put in with the reader. I tried doing it on my wife's computer, but still nothing. I also tried another card in the reader, and it worked fine, so I know the reader is functioning okay. Any suggestions what I could do? Is the card just toast for some reason perhaps?
