MY WINDOWS 10 COMPUTER DOES NOT DETECT MICRO SD CARD INSERTED IN THE SLOT

Hi, i hope you're doing good today.

Let's try the following and see if some of these methods works for you.

1. Try SD Card on Another Device
Sometimes it is the computer interface that breaks, rather than SD card. In this case, just connect your SD card to another computer or Android phone. Alternatively, try another SD card to check the interface. There is no shortcut if you want to test the SD card not recognized or working on Windows 10.

2. Check SD Card in Disk Management
If your SD card doesn’t show up in Windows 10 File System, but in Disk Management, check whether there is a drive letter for the card. Follow the steps below to add a drive letter:
Step 1. Right click “My Computer” and select “Disk Management”.
Step 2. In Disk Management, your SD card will appear as a removable disk. Check if it has a drive letter like D or E.
Step 3. If not, right click the SD card and select “Change Drive Letter and Paths”.
Step 4. Click “Add” and select a drive letter, then click “OK”. Your SD card would be working in File System along with local disks.

3. Remove SD Card Write Protection
There is a knowledge point that write protected SD card will not be displayed on other devices, except the original one. So if you did lock your SD card before, the first thing is to remove write protection from SD card. Check the lock switch beside the card or use disk utility. It can also fix SD card not showing up on Windows 10.

4. Reinstall/Update SD Card Driver
When you update Windows 10, it will automatically renew all device drivers. But if you still have problem with a device, it is still well worth a try to update or reinstall the driver. Here’s how to update/reinstall driver to repair (micro) SD card not detected on Windows 10:

Step 2. Find your SD card and right click it, then select “Update Driver”.
Step 3. Select “Search automatically for updated drive software”. If there is no new driver, try to look for one on the manufacturer’s website and follow the installation wizard.
Step 4. If it doesn’t work to update driver, just right click the device and select “Uninstall”. Then restart your computer, and Windows will reinstall the driver by itself.

5. Enable SD Card Reader
Disabled SD card will not show up on Windows 10. The steps to enable this function are the same as above. First find your SD card in “Device Manager” and right click it. If it shows “Disable Device”, then you have already enabled SD card reader and there is no need to do anything. If not, just select the option “Enable Device”. Then Windows 10 could detect your SD card normally.

6. Run Hardware and Device Troubleshooter
