I've been using my HTC desire 626 on ATT android for about 2 years. Always store music movies and maps on the data card, which is about 50% of 32GB full. Yesterday the data card stopped being recognized. Have tried all possible combinations or removing the card, inserting the card, and rebooting. Also tried reformatting the card to no avail. When I insert the card in my computer it works fine so it isn't the card. When I do settings/storage/mount SD card get a message "SD card is safe to remove"
