The dead SD card not showing up on Windows, how to fix?
If unfortunately, your SD card can't be recognized or read by a Windows computer, there's no response when plugging the SD card into your PC, or, the SD card not showing up in Windows at all, and you consider it as if your SD card is dead.
Well, it is fair enough. But actually, the SD card is not 'dead', the improper connection and outed disk driver may be the culprits, and due to this, your PC fails to recognize your card. In this situation, you can try these solutions to make your computer read the SD card.
Solution 1: Check the connection
When a connected SD card doesn't appear on your computer, the first thing you should do is to check the connection, and see if the card is connected loosely or improperly. If it doesn't work, then maybe your SD card reader is not working.
Also, dust particles would get accumulated over your SD card's connectors over time, which prevents the computer to recognize and read it properly. So you can wipe any dust or other particles off the SD card surface and its connector, and reconnect it to your computer to see if the problem still exists.
Solution 2: Update the disk driver on your computer
If the SD card driver is outdated, your PC won't be able to recognize your card, thus it will not be displayed in either File Explorer or Disk Management. So, all you need to do is to update the driver on your Windows computer. Here's how:
- Connect your dead micro SD card to your Windows PC.
- Press Windows and R keys on your keyboard at the same time, and a dialogue box appears. Type devmgmt.msc on the dialogue box and click OK to launch the Device Manager.
- In the Device Manager window, click on Disk Drivers from the left panel and right-click on your dead micro SD card, then select Update Driver.
