I tried searching for this but didnt see it yet. I was trying to set up Wifi for Mario Kart DS, and went to "delete" one of the settings. The system froze. I restarted, and it gave me a SD/TF Card Error. I copied all my savs to my PC then. I've since reformatted the card and put the data back on and it still doesn't work. It's a Kingston that has been working fine until I tried that. Has anyone experience this, or does anyone have anything to try?
