I purchased a 32gb micro SD card class 10 to dump music in for my S II. It came with an adapter to be able to plug into my computer. I did so and loaded it with music (took about 3 hours). Once I ejected the SD card and entered it in the phone and only 18 folders out of 324 of music appeared. I tried it again. I removed the SD card from the computer then replugged it back in to see if it was the SD card. But the files only disappear when I enter the SD card into my phone. Help?
