    Welcome to Android Central! You're talking about an 8 GB external microSD card, right? Does it even show up in the Settings>Storage menu?

    Try removing the card (Unmounting it first in the Settings>Storage​ menu, if you see the option), then insert it into your computer (using a fullsize SD adapter), and see if your computer can read it.
