How to Resolve ERROR_DATA_CHECKSUM_ERROR Issues

The ERROR_DATA_CHECKSUM_ERROR signal indicates potential data integrity issues that may arise during data transfer or when data is being saved. It is identified by the code 323 (0x143) and indicates that a checksum error has been detected, resulting in a “Data in the file stream is corrupt”message.

This error typically occurs when the computed checksum for data does not correspond to the expected checksum value, which means the data might have been corrupted in transit. Common reasons for this error include interrupted downloads, unstable internet connections, sudden system shutdowns, or power outages. Additionally, issues such as faulty sectors on the hard drive or insufficient storage space can also lead to this error.

How to Resolve ERROR_DATA_CHECKSUM_ERROR?

1. Execute Check Disk Utility (chkdsk)

1. Press Windows + X and choose Terminal (Admin).
2. Enter the following command (substituting C: with the affected drive letter): chkdsk C: /f /r /x then hit Enter.
3. Follow the instructions displayed on-screen, and restart your computer after the scan is complete.

Running a disk error check is the initial step to take when encountering the ERROR_DATA_CHECKSUM_ERROR, and it often resolves the issue.

2. Perform System File Checker (SFC) and DISM Scans

1. Press Windows + X and select Terminal (Admin).
2. To initiate an SFC scan, input the command: sfc /scannow and press Enter.
3. If the error continues, execute DISM to repair the Windows image with the command: DISM /Online /Cleanup-Image /RestoreHealth.
4. Restart your machine once the processes are completed.

Since the ERROR_DATA_CHECKSUM_ERROR can arise from filesystem corruption, using SFC and DISM will check for and rectify any related problems.

3. Inspect and Replace Defective RAM

1. Press Windows + R, input mdsched.exe, and press Enter.
2. Select Restart now and check for problems.
3. If issues are found, you may need to consider replacing the RAM.

Faulty RAM could be a contributing factor to checksum errors. Along with utilizing the Windows Memory Diagnostic tool, you can physically check and reseat the RAM sticks in their slots if you have access to the PC’s interior.

4. Update or Reinstall Disk Drive and Storage Controller Drivers

1. Press Windows + X and select Device Manager.
2. Expand both the Disk drives and Storage controllers categories.
3. Right-click each device and choose Update driver.
4. After updating all necessary drivers, restart your computer.

You can also visit the website of your disk drive’s manufacturer to download the latest drivers suited for your system. If no new drivers are identified, ensure your Windows updates are fully installed, and consider using a driver update tool to automate the process, saving time over manual updates.

If these methods do not resolve the issue, consider performing a clean installation of Windows 11 as a last resort.

We trust that the aforementioned steps assisted you in resolving the ERROR_DATA_CHECKSUM_ERROR, restoring your system to normal operations. Should you have further inquiries or suggestions, please feel free to share in the comments section below.
