Hi I’m also having the same issue on my Note 2. I bought the 32GB from a reputable local store just a few months ago. After I’ve copy my file to the memory card, it work perfectly for almost a month. Then, I started receiveing different kinds of messages like : a blank SD card was inserted. The card contains some invalid format. jIt is asking me to format the card. When I tried to format the card using the phone, pc, and mac, it is not allowing me to do so. Now, the card reader can’t even recognized the card.
