When i go into settings on the tablet and hit mount sd it clicks and then quickly shows 0% and mount sd card shows up again. And says damaged sd card.

    Welcome to Android Central! The SD card could be corrupt, defective, or counterfeit. Install SD Insight to see if the card is genuine or counterfeit. Counterfeit cards are programmed to report more storage than they actually have, and if you try saving more than the card can actually hold, then files can start getting corrupt. (Be aware that SD Insight might not work on all Nougat devices.)

    If it's a valid card, then go to Settings>Storage, Unmount the card, remove it, and insert it into your computer. Can the computer read these files? Backup as much as you can right now, then run chkdsk to look for bad sectors: http://forums.androidcentral.com/amb...d-sd-card.html.

    If nothing can read the card, then it's dead. SD cards don't last forever, and they have a higher failure rate than onboard memory. Hopefully, you weren't using it as the only storage location for important data.
