CHKDSK checks the file system and changes any logical errors it finds. It could give you back access to your data and fix corruption problems. This method usually fixes small disk errors and is the first thing you should try when you have issues with an SD card.

Method 2. Connect to A Different Device

Sometimes, being unable to reach an SD card could be because the device isn't compatible or has driver problems. Putting the SD card into another device that works with it can help you determine if the issue is with the card or how the device is set up.

You can check to see if the SD card is identified and recognized by putting it into a different computer, camera, or card reader. If the card works well on another device, the issue might be unique to the first device, meaning its drivers or settings must be investigated further.

Method 3. Give The SD Card A New Drive Letter

Assigning a new drive letter can often fix problems where the SD card is found but can't be accessed because of different drive assignments. To do this, open Windows's Disk Management tool, see the SD card and change the drive letter given.

Right-click on the SD card, and then you will select "Change Drive Letter and Paths" to give it a free drive letter. Once given, the SD card should appear in File Explorer with the new drive letter so you can easily access its contents.

Method 4. Format The SD Card

Formatting the SD card is a drastic but effective way to fix serious corruption problems or mistakes that won't go away. By formatting the card, you delete all the data and return it to how it was first made. It also removes any damaged files or data you can't access.

You can use either the Windows formatting tools or third-party formatting tools to format the SD card. Ensure you have a backup of any important data on the SD card before you format it because you can't get it back once you do. You will lose all of your files and groups.

Step 1. Open Disk Management (Right-click This PC > choose Manage > Computer Management > Disk Management)

Step 2. Find the SD card, right-click it and choose Format. Then select ExFAT or FAT32 as the file system, format it.

Once the driver has been removed, please restart the computer so Windows can install it again immediately. You can also get the latest version from the car's maker's website. Reinstalling the driver ensures that the device can talk to the operating system properly, which could fix any problems with recognition or compatibility.
