Method 1: SD Card Corrupted Recovery by Testing Another Reader or Device

Sometimes the issue isn’t with the SD card itself but with the card reader or the USB port.

Insert your SD card into another reader or computer.
If the data is accessible, your card is fine—the problem was with the reader.

This quick check helps rule out hardware connection issues before trying deeper recovery methods.

Method 2: SD Card Corrupted Recovery with Windows Error Checking

Windows has a built-in error-checking tool that can fix minor file system problems:

1.Right-click the SD card drive in File Explorer.

2.Select Properties > Tools > Error Checking.

3.Allow Windows to scan and repair detected issues.

This is a beginner-friendly first step that often resolves simple corruption.

Method 3: SD Card Corrupted Recovery with CMD

One of the most effective ways to fix a corrupted SD card is through Command Prompt (CMD). Many IT technicians and Microsoft community experts recommend this built-in method because it directly addresses file system errors.

1.Connect the SD card to your PC.

2.Press Win key on the keyboard, type “CMD“, and run as administrator.

3.Enter the command:

chkdsk G: /f /r

(Replace G: with your SD card’s drive letter)

This command will scan the SD card, repair logical errors, and recover readable data clusters. However, it’s important to note that this process modifies the file system, and in some cases, may cause further data loss if used incorrectly. For detailed guidance, you can also check the official Microsoft documentation on CHKDSK.If you are not confident using CMD, consider starting with professional corrupted SD card recovery software for a safer approach.

Method 4: SD Card Corrupted Recovery with WinHex for Advanced Users

For users proficient with technical tools, hex editors like WinHex offer advanced, deep-level SD card recovery capabilities. Numerous factors can cause SD card partition damage, but the underlying principles remain the same. Below is a straightforward recovery example for reference.

1.Check the partition status in Disk Management (right click Start — Disk Management)

2.If the SD card displays as RAW, it typically indicates a corrupted file system, requiring an examination of the DBR. The DBR contains critical file system information, which is located in the first sector of the volume.

3.Based on the boot sector analysis, the file system appears damaged. For FAT32, the backup sector is located on the sixth sector. Access the sixth sector, which appears to be intact.

4.Copy and replace the hex values to the correct location.

5.Save and refresh Disk Management. We can see the file system has been fixed.

This method is highly effective but not beginner-friendly, as it demands familiarity with file systems and partition structures. A single error can exacerbate the corruption.

If CMD or WinHex feels too technical, specialized software such as Magic Data Recovery offers a user-friendly and highly reliable solution.
