Went to listen to my music today and nothing was showing up. Opened ES file explorer and sure enough the card was not being recognized. I took it out put it in my computer that once did recognize and transfer files with the card and it also no longer recognizes it. I did some research and it seems this happens a LOT with Samsung Galaxy's and Note's. I did not have any important files, but I would like to somehow reformat the card so I am not out 40 bucks. Thanks so much!
