My micro SD card(which worked fine for two years on my LG Optimus S) has stopped being recognized by my Galaxy S3 after about 3 months of use with no problems. It occurred very randomly, I don't believe I was even using the phone when it happened. I just wanted to check my pictures on my SD card one day and they were all gone... I am unable to mount the SD card, as it tells me to insert one. After hooking up the card to the computer, I tried to click on it and it tells me it's inaccessible because it is write protected! I've ensured that the little lock thing is unlocked and all that. I don't believe I have a recent backup of this card... Am I SOL?
