Why is my Samsung 32 EVO micro sdcard not being recognized?

[AC Question]

I have purchased it from Walmart and it was my second buy. Idk why these cards are operable for a short time and then they just stop.

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.


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/am...guide-using-chkdsk-fix-corrupted-sd-card.html.

Also, which phone do you have? Certain older Samsung phones were somewhat notorious for causing SD corruption on occasion.
