  • Run chkdsk [SDCard Drive Letter] /r where [ ] is where you will put the drive letter. so the example will look like this chkdsk D: /r Example drive letter being D run that then try your card. – NetworkKingPin Apr 26 '16 at 11:51

    If two cards have become damaged it would suggest that the card reader in the phone is broken. – Burgi Apr 26 '16 at 13:55

The grand prime is known to cause electrical damage to sd cards and without warning. I have two of these phones and they each destroy an sd card every 3 months. The cards may have self sensed damage and dropped into read only mode, in which case you can read them with a usb reader on a desktop but the phone will refuse to mount at all, and the will not be writable in any case.


Sounds like it's the card reader in the phone if the cards are working perfectly with other card readers. Also alot of people with the grand prime have been having the same problems at you.
