So I have a galaxy s5 and the sd card that is in my phone has been there for several months. I didn't remove the card or make any changes, but yesterday I get a msg that card is blank or unsupported file system. Not sure why I'm getting this msg. I took the card out, made sure the slot and the card were clean. Put it back in and same msg, so I put it in a different phone to see if it would read. I got the same error msg. At this point, I just want to recover the 3000+ pictures and videos I have In There but when I plug the phone into my laptop, it don't see the sd card. Anyone have a suggestion on how to recover the sd card data?
