3DS Could Not Detect an SD Card issue

Today while playing Style Savvy, my battery was low so I plugged in to and continued to play a bit. When I took a picture in-game, I received the "Black Screen of Death". Since, I needed to turn off the system anyway, I just set it down to finish charging. After a while, I tried to turn back on the system, but I received the SD card could not be detected message. I tried restarting the system, taking out the SD card and putting it back in and nothing works. However, when I try to plug my SD card into my computer, my computer tells me "You need to format the disk in drive H before you can use it". My SD card is a PNY Professional 32GB SD (SDHC) Class 10 Flash Memory Card. Any help would be useful!
