Moonshell bricked my SD Card?

I'm having alot of trouble with my sd card. It started when I used moonshell 2.09 and was playing music and accidentally tried to play the moonshell nds file thinking I was in the flashcard gui momentarily. Moonshell of course crashed and now won't reboot without giving be a fatal error, telling me to format the sd card. The card shows up in my computer but can no longer be read on my pc in either windows or linux and so I cant even format it. However I am running itouchds latest firmware and the sd card boots into itouchds and options as well as any homebrew just fine. Is there anything I can do to fix this or a better place to get help?
