Solved: SD card wont mount error on Android

SD card won't mount, gives error message



 I have a new M4 Aqua that won't mount an SD card. I have tried 2 different SD cards, one that is 2 years old and works fine in other phones and one brand new one. Of course I have tried reformatting/erasing the cards both in the phone and on a computer, the diagnostic tool in the computer tells me the cards are fine, but when I try to mount the cards I get the message, "SD card is damaged. Try reformatting it." 

Thanks for any help.
