i used my micro sd card in my s5 for about a month until it decided to 'unmount' itself. I did not take it out unexpectedly, it just stopped working. I have tried putting it in an adapter on my laptop but it wont show up. I have also tried other devices. This is the seocnd sd card that this has happened to in my s5. How can i recover my files???? it wont even show uppppp
