How to repair undetected micro SD card in Windows 10 easily

The issue of micro SD card not detected in Windows 10 can be caused by different reasons. Before you turn to specific solutions, you should check whether it’s the problem with the micro SD card or the computer. Just connect your SD card to another computer or connect another SD card to the same computer to find out.

If it’s the problem with the micro SD card, wrong format of the SD card can be the cause. You can format the SD card in a universal FAT32 format with SD card formatter FAT32, thus making it detected by Windows. Do backup files before reformatting to prevent data loss. If it’s the problem with the computer, there are three solutions for your reference:

Solution 1: enable SD card reader
Solution 2: update/reinstall SD card driver
Solution 3: run hardware and device troubleshooter

Disabled SD card reader will make SD card not detected in PC. You can check and enable it with following steps:

1. Right click on the Start icon and select Device Manager.

2. Find your micro SD card and right click on it.
