Hi Rusty, I formatted the card on the computer becuase the GOPRO just freezes so i cant format it on the gopro. it is brand new and the card came with the gopro. after i formateed it it worked briefly - I took one test photo and then charged the camera. when i came to switch it on again it said "No SD" in it. i then tried to do an update online to try and fix it and that failed.
