I bought my gopro 3 black on March 1 with the 64gbs sandisk memory card that gopro recommends. I’ve done the last firmaware update on April 8. Today, 25 of April, It happens to my card. I put the camera recording and she automatically stop recording, for 3 times. I started to get worried with that so I turnt the camera off and on again. and it was there that appears SD ERR on my Gopro. I tryed format the card on the camera and nothing. I turned off the battery a few minutes and card too, and the error still there. Then i went home, run to my computer to try format the card. The files are there and i can play it on windows video player and copy to my pc, but i can not delet them or format the card . it says " windows could not complete the format"…
GOPRO and Sandisk have to assume the problem!!
