Fix Data Error (Cyclic Redundancy Check) on Windows 10
When using Windows 10, you may encounter the message "Data error (cyclic redundancy check)". This usually indicates data corruption or a physical disk failure. This article will introduce several effective methods to fix this error, helping you recover data and resolve disk issues.
1. Check Device Drivers
Outdated or corrupted drivers may cause system instability, leading to the "Data error (cyclic redundancy check)" issue. Checking and updating your device drivers in a timely manner is an effective way to resolve this problem. Using Driver Sentry to automatically detect and update drivers can save time and prevent downloading or installing incorrect drivers.
Click the download button to get the latest version of Driver Sentry. After installation, open the software and click "Scan".
Once the scan is complete, the software will display missing or outdated drivers. Locate the necessary driver updates in the list and click "Upgrade".
After updating, restart your computer to ensure the new drivers take effect properly.
2. Run the CHKDSK Command
Press Win + S, type "cmd" in the search bar, right-click Command Prompt, and select "Run as administrator".
In the command prompt window, enter the following command and press Enter: chkdsk C: /f /r
Explanation:
Replace C: with the affected drive letter (such as D: or E:).
/f fixes disk errors.
/r identifies and repairs bad sectors and attempts to recover readable data.
If prompted, type "Y" and restart your computer to allow CHKDSK to run at startup.
After CHKDSK completes, check if you can access your files or perform previous failed operations.
3. Run SFC and DISM Tools
Run the SFC Command:
Open Command Prompt as an administrator (refer to CHKDSK steps).
Enter the following command and press Enter: sfc /scannow
Wait for the scan to complete. Windows will automatically detect and repair corrupted system files.
If SFC fixes any files, restart your computer and check if the issue is resolved.
If SFC fails to repair all files, proceed with the DISM command.
Run the DISM Command:
Open Command Prompt as an administrator.
Enter the following commands one by one: DISM /Online /Cleanup-Image /CheckHealth
This checks if the Windows image is corrupted but does not repair it.
If corruption is detected, run: DISM /Online /Cleanup-Image /ScanHealth
This scans the Windows image for issues.
If damage is found, repair it by running: DISM /Online /Cleanup-Image /RestoreHealth
This command downloads and replaces corrupted system files (requires a stable internet connection).
Once completed, restart your computer and check if the issue is resolved.
4. Check Disk Connections
Shut down the computer and disconnect the power.
If using an external hard drive, try switching USB ports or replacing the data cable.
If using an internal hard drive, open the computer case and check if the SATA/PCIe cables are loose or damaged.
If using an SD card or USB drive, test it on another device or with a different card reader.
Reconnect the disk, power on your computer, and check if the issue is resolved.
If the problem persists, check if the disk is recognized correctly in the BIOS settings.
5. Format the Disk
Open File Explorer (press Win + E).
Right-click the affected drive and select "Format".
In the format window, configure the following settings:
File System: Choose NTFS (for Windows) or exFAT (for cross-platform compatibility).
Allocation Unit Size: Leave it as the default value.
Format Type: Check Quick Format (for minor issues) or uncheck it for a deep format (if errors persist).
Click Start and wait for the format process to complete.
By following these steps, you can usually resolve most CRC errors. If the issue persists, consider contacting a professional data recovery service or replacing the storage device.
