Overview

The card reader is an important bearer connecting computer and memory card, which plays an important role in life and work. When an SD card reader can’t work normally on Windows, need we take action to fix it? Yes, because there are several reasons causing SD card readers not to work on Windows 10:

  • The dust/oxide layer of the card reader prevents it from working.
  • The USB port of your computer is corrupted.
  • The Windows card reader driver is faulty or system files are lost.
  • Viruses or malware attack the SD card, causing the SD card to be unrecognized.

So, when you are facing the SD card reader not working issue, we need to troubleshoot and avoid the issue happening again.

Methods To Fix SD Card Reader Not Working

Method 1: Use Different USB Ports

The problem causing the SD card reader issue could be a USB port. Some computers have multiple USB ports. Try to read USB cards by swapping slots or using USB ports on different computers. You can fix the “cannot read SD card” error by switching the USB port.

Method 2: Check and Clean SD Card Reader

If you have or haven’t used the SD card reader for a long time, you should check if the SD card reader is too dusty to work. You can clean the SD card reader using cotton moistened with alcohol, a dry soft-bristled brush, or simply your breath. Be careful and don’t scratch the metal contacts inside the SD card reader slot.

At the same time, to check for any damage to your card reader, you can try the following:

  • Use another external card reader and check whether your PC can read SD cards.
  • Try to access the SD card on another computer’s built-in card reader.

If you can use the above two methods to read the SD card, it means that your card reader is faulty. If your computer still can’t read your SD card, try again.

Method 3: Restart Windows 10 Computer

This is the simplest method, but it’s also a viable one for everything, and restarting your computer is a tried-and-true solution that surprisingly solves most problems users encounter. Disconnect the card reader from the computer, then reboot and reconnect. Check if the problem still exists.
