How do I repair an SD card which shows the incorrect size?

If your SD card is showing an incorrect size, it could be due to various reasons, such as file system corruption, partition issues, or physical damage. Here are some steps you can take to attempt to repair an SD card with an incorrect size:

Check the Physical Condition:

• Ensure that the SD card is not physically damaged. Inspect the card for any visible signs of damage, such as cracks or bent pins.

Use Windows Disk Management:

• Connect the SD card to your computer and open Disk Management (you can search for "Disk Management" in the Start menu).
• Find the SD card in the list of drives. It might show unallocated space or an incorrect size.
• Right-click on the SD card partition and choose "Delete Volume."
• Right-click again on the unallocated space and choose "New Simple Volume" to create a new partition.

Format the SD Card:

• After creating a new partition, you can try formatting the SD card to its correct capacity. Right-click on the SD card partition, select "Format," and choose the appropriate file system (FAT32 or exFAT for SD cards).

Use DiskPart in Command Prompt:

• Open Command Prompt as an administrator.
• Type diskpart and press Enter.
• Type list disk to display a list of all connected drives.
• Identify your SD card (be careful to select the correct disk).
• Type select disk X (replace X with the disk number of your SD card).
• Type clean to remove all partitions from the SD card.
• Type create partition primary to create a new partition.
• Type format fs=FAT32 or format fs=exFAT to format the SD card.
• Exit the Command Prompt.

Use Repairing Software Tool:

• There are various tools designed for repairing and formatting SD cards. Tools like SD Card Format and Wondershare repairit may help in resolving size-related issues.

Update or Reinstall Drivers:

• Ensure that your SD card reader drivers are up to date. You can check for driver updates in the Device Manager.

Use a Different Card Reader or Computer:

• Try using a different card reader or connecting the SD card to another computer to rule out issues with the card reader or your computer's USB port.

Important Notes:

• Make sure to back up any important data on the SD card before attempting any repair or formatting, as these actions may result in data loss.
• If the SD card continues to show incorrect size after trying the above methods, there might be a hardware failure, and professional data recovery services may be needed.
