I was recording videos, then when I went to upload them to my computer it my camera (Nikon D5100) showed a message that said I couldn't use the card because it was damaged. I know that I have to format the memory card now to get it working but neither my pc and mac detected the memory card.so how can I format it if the computer doesn't detect there is a memory card ?! Please help! The user's manual only says what I already know, not helpful lat all
>>> SD memory card damaged?
