So, had my CFW perfect on my comp with the help of a very nice person I met here. Everything was working fine, until today when i took the sd card out to put a CIA file on it. When I put it back in the 3ds, it just kept saying micro sd card could not be found. Then I put the sd card into the computer, and it instantly says it needs to be formatted. Is there any way to fix this or am I screwed? Does this mean I need to format it and start all over again? I was only able to do it because the extremely nice person I met here walked me through it step by step. Really hoping there's a way to somehow recover the card.
