2. Use a Different USB Port or Adapter

This is another method that’s relatively easy to fix a damaged SD card without formatting it. If your SD card is not recognized by your computer, try connecting it to a different USB port. If that doesn't work, try using a different adapter or card reader. Connect the SD card to another computer using a USB card reader, trying different USB ports on multiple computers for better chances of success. This will help you to rule out the possibility that the problem is with your laptop's SD card reader.

Additionally, check if the microSD card adapter is causing the issue by trying a different adapter or connecting the microSD card directly to your computer using a microSD card reader.

4. Use a CHKDSK Command.

The CHKDSK command is a built-in Windows command that can be used to scan and repair hard drives and other storage devices. You can use CHKDSK to scan your SD card for errors and attempt to repair them.

Step 1: Open the Command Prompt by typing CMD in the search bar next to the Start button.

open the command prompt

Step 2: Connect your SD card to the computer using a card reader or through a camera/smartphone. Note the drive letter assigned to the SD card.

Step 3: Copy and paste the following command into CMD, replacing "Z" with the drive letter of your SD card:

chkdsk Z: /f

enter the command

Step 4: Next, copy and paste the command below into CMD, making sure to change "Z" to the correct drive letter:

attrib -h -r -s /s /d Z:*.*

After completing these steps, check your SD card. If your files are recovered, the method worked; otherwise, try the next method.

5. Using Windows Repair Tool

Windows includes a graphical tool called Windows Repair Tool that can be used to check drives for file system errors. This tool is sometimes automatically launched when you insert a corrupted drive. Alternatively, you have the option to manually invoke it and perform a scan on any drive for errors.

To fix a corrupted SD card using Windows Repair Tool, follow these steps:

  • Open File Explorer.
  • Right-click on your SD card and choose "Properties."
  • Click the Tools tab.
  • Click the Check button.
  • Click the Scan and repair drive button.

If a message appears, saying Windows can't fix the drive while it's in use, save any unfinished work on the SD card. After that, select whether to repair it immediately or during the next restart.

6. Create a Partition on an SD Card

If your SD card is not showing up in File Explorer, it may be because it does not have a partition. A partition is a logical division of a storage device, and it is necessary for the device to be recognized by Windows.

To create a partition on an SD card, follow these steps:

  • Plug in the SD card to your computer.
  • Press the "Win + X" keys together and choose "Disk Management" from the menu.
  • Right-click on the SD card and select Create a New Simple Volume.
  • Follow the step-by-step partition creation wizard.

Once you have created a partition, your SD card should be recognized by Windows and you will be able to access the files on it.

7. Assign a New Drive Letter

Corrupted SD cards can sometimes be fixed by assigning a new drive letter to the card. This is because corrupted SD cards can sometimes cause conflicts with other drive letters, which can prevent the card from being accessed.

To assign a new drive letter to an SD card, follow these steps:

  • Open Disk Management and enter Create and formate hard disk partitions
  • Recover data from corrupted SD card
  • Select the SD card, right-click on it, and then choose "Change Drive Letter and Paths."
  • Click the Change button.
  • choose a new drive letter and click OK.
  • Click OK again to close the Change Drive Letter and Paths window.

8. Format the SD card

Formatting is a way to fix a corrupted SD card by replacing the faulty partition table with a new one and recreating a damaged file system. Formatting an SD card can be done using the built-in formatting tool in Windows.

To format a corrupted SD card:

  • Open File Explorer.
  • To format your SD card, right-click on it and choose "Format."
  • In the Format window, select the preferred file system, and you can leave the Allocation unit size unchanged.
  • Uncheck the Quick Format option.
  • Click Start to format the SD card.

The main difference between Quick Format and Full Format is that the Full Format scans the formatted device for bad sectors, while the Quick Format only removes address files from it.

3. Reinstall SD Card Drivers

Windows typically automatically downloads and installs the latest drivers through Windows Update. However, in case of issues with your SD card due to a faulty driver update, consider manually reinstalling the driver to resolve the problem.

To reinstall SD card drivers, follow these steps:

  • Open Device Manager.
  • Open Device Manager
  • Expand the Portable Devices category.
  • Right-click on your SD card and select Update driver.
  • Update driver
  • Select Search automatically for updated driver software.
  • Update driver
  • Windows will search for the latest driver for your SD card. If it finds a suitable driver, it will install it automatically.

If Windows does not find a suitable driver, you can look for it on the manufacturer's website and install it manually.
