I tried reformatting my Micro SD card (in disk writer )to try to change the card back into NTFS but windows will not show the card back again. Tried using partition wizard after reformat and card is shown as bad drive. Removing and reinserting the card back into the computer brings me back to step one. Additionally, I cannot add or remove games at all on the current SD card. The current games on the card can be played on the 3DS though. I tried 2 SD card readers still no difference. Reformatting it in other devices shows the card as locked. Is there anyway to save this SD card?
