computer won't recognize sd card

Have you tried to reinsert your SD card multiple times, but still wondering why your SD is not showing up on your Windows 10 or Windows 11 OS? If your computer doesn’t recognize the SD card or says “SD card not detected” after you insert it into the PC, there are a few easy fixes you can try.

However, before you try to access your SD card by applying fixes, it’s important to recover data on your SD card just to be safe. In this guide, you’ll learn how to recover data and fix your SD card within minutes.

Is It Possible to Fix SD Card that Is Not Detected?

The possibility of recovering an SD card that is not detected by your computer depends on the underlying reason why it became undetectable. This specific scenario will also determine how you can recover data from your SD card and how successful the recovery will be.

To shed light on this, let’s explore the different degrees to which your SD card can be undetectable:

  • Your SD card is not detected in File Explorer but can be seen in Disk Management. In this scenario, you cannot access your SD card and its contents, but the drive is still recognized by your computer when you check for it via Disk Management.
  • Your SD card is not detected in Disk Management but can be seen in Device Management. In this case, formatting your SD card might be extra challenging since Device Manager does not have the functionality to do this.
  • SD Card is not detected in Device Manager. When your SD card cannot be detected even in Device Manager, it might mean that your storage device is physically damaged or dead. Fixing a dead SD card is extremely challenging, if not impossible.

Before troubleshooting your SD card, it’s also important to understand why your PC is not recognizing it. You can start with these common scenarios and the possible reasons behind them:

How to Fix SD Card That Won’t Read

Once you’ve recovered the files, you can start fixing your SD card. Your SD card may not show up on your Windows 10 computer for several reasons. Therefore, the fix depends on the cause. You can try to fix the problem in the following ways depending on what is causing the SD card to not show up:

Method 1: Check the Card Reader

Before you blame your SD card, check if your card reader is working properly. Try inserting a different card into the card reader and see if your PC detects the SD card and is able to read it properly.

If the other card doesn’t work either, clear any accumulated dust from the card reader. If cleaning the card reader doesn’t work either, plug the card reader into a different USB port to confirm if the card reader is functioning properly.

Method 2: Restart PC

As simple as it may sound, a restart might just fix your issue. Disconnect the card reader, restart your PC, and then plug it back in once your PC restarts.

Method 3:Disable and Enable the SD card Reader Device

Sometimes, just enabling and disabling the device does the trick. You can enable and disable the SD card reader from the Device Manager.

  1. Search for device manager in the Start Menu and open the Best Match.

  2. Look for your SD card reader in the list of devices. It should be under Memory technology devices. If you don’t see this category on the list, click on the tiny arrow to the left of Disk drives. You’ll see your SD card under Disk Drives. Right-click on it and select Disable device.

    disable sd card device

  3. Next, right-click again and select Enable device.

If this doesn’t fix the problem, try updating the drivers.

Method 4: Update Drivers

Windows almost always automatically installs drivers for all devices that you plug in. However, if the manufacturer has rolled out an update later to fix bugs, installing them can potentially fix your problem. You can use the built-in driver update feature in Windows, but if that doesn’t work, you’ll need to look through the manufacturer’s website to see if there’s a newer version of the driver and install it.

To try updating from within Windows, you’ll again need to use the Device Manager.

  1. Right-click on the SD card or SD card reader in the Device Manager and select Update driver.

  2. Windows will ask if you want to search automatically for drivers or browse the computer for drivers. Select the first option.

If Windows finds any updated drivers, it will install the drivers automatically. However, Windows isn’t that great at finding drivers. If it says the best driver is installed already, try looking through the manufacturer’s website for an updated driver.

Method 5: Format SD Card

Formatting is often the most foolproof option to fix an unreadable SD card, given that you can still see it in Disk Management. This process erases all the data from your card and resets its file system configuration, among other settings.

Here’s an easy guide to format your SD card:

  2. In the lower section of the program, you will see a list of all your connected devices. Locate your SD card. Then, right-click on it and choose Format.Formatting the SD card using Disk Management.

  2. Locate your SD card on the list of disks and partitions. Then right-click on it and select Change Drive Letter and Paths.Change drive letter and paths
  3. Click Change. This opens another pop-up window where you can choose the drive letter.Select the Drive letter and click OK

Your phone may not read an SD card for the following reasons:
  • The card has been physical damaged
  • Built-in SD card slot in your phone has been damaged
  • Dusty or dirty SD card slot
  • SD card has been infected with a virus
  • SD card has become corrupted
Accessing an SD card on Windows isn’t much different from accessing a flash drive. If you’re using a laptop with a built-in SD card reader, insert your card into the slot. If you’re using an external SD card reader, connect the card reader with your PC and insert the SD card into the card reader. Your PC will automatically recognize the SD card. However, you can also access the SD card by navigating to This PC on Windows 10.
The most common reason why an SD card freezes your Windows 10 is because of an outdated driver. Try updating your SD card driver to fix the issue. However, if it doesn’t fix the problem, the reason could be that the SD card has become corrupt. When Windows detects an SD card, it initiates a process known as mounting. Windows will try to read the card’s metadata from your card’s sectors, and a bad sector will cause the process of mounting to hang and consequently freezing your computer. If you’ve connected an SD card reader with your PC and the SD card won’t mount, Windows will automatically disconnect it after a while if it can’t move the process forward.
You typically don’t need to “enable” an SD card on Windows 11. Once you connect your card to a computer via an SD card slot/SD card reader, it should automatically be recognized and its contents be accessed via the File Explorer. However, if your computer doesn’t recognize your SD card, you can try simple fixes like reinserting your card into the card reader/slot, cleaning your card, restarting your computer, or updating your drivers.
If your Android device cannot recognize your SD card, you can try turning off your device, reinserting your card, and turning it back on to check if your card can now be recognized. You can also clean your SD card or your SD card slot to make sure no dust or dirt is preventing your Android device from reading your card properly. If none of these methods work, try formatting your SD card from your Android device. Simply go to Settings > Storage > Format SD card if the option is available.
If your micro SD card is not detected by your computer, you can try these quick fixes:
  • Reinsert your card into the card reader/slot
  • Restart your computer and reinsert your SD card
  • Update your SD card drivers
  • Disable and enable your SD card reader device from Device Manager
  • Repair your SD card by running CHKDSK
If these methods did not work, formatting your SD card is your best option. However, this will erase all the files from your card.
