So yesterday I was taking a bunch of pictures. Then my phone says the SD card is not inserted anymore. I thought that's strange. So I took it out and inserted it back in and rebooted it. Same thing. I plugged my phone into the computer... I can't find my pictures ANYWHERE ON MY EXTERNAL SD CARD!! I DIDN'T DELETE THEM! Yet all my music is still on my external SD card. Can anyone help me PLEASE??? I'm desperate.
