Ultra DMA (UDMA) CRC (Cyclic Redundancy Check) errors are common indicators of data transmission issues between your storage device (such as HDD or SSD) and the host controller. If you’re encountering the UDMA CRC Error Count issue, follow these troubleshooting steps to resolve it effectively.
What Causes Ultra DMA CRC Errors?
UDMA CRC errors typically signify problems with:
- Loose, damaged, or faulty SATA cables.
- Outdated or corrupted device drivers.
- Problems with disk or motherboard SATA connectors.
- Outdated system BIOS.
If the CRC error count increases frequently, addressing it promptly is essential to prevent data corruption or loss.
Methods to Fix UDMA CRC Errors:
Method 1: Check Your SATA Cable and Connections
- Power off your computer.
- Open the case and verify the SATA cables connecting your HDD or SSD are firmly seated and undamaged.
- Replace cables if necessary, ensuring a secure connection.
Method 2: Update or Reinstall Drivers
- Press
Windows + S, type “Device Manager,” and open it. - Expand the
Disk Drivessection, right-click your drive, and select “Update Driver.” - If this doesn’t resolve the issue, try uninstalling and reinstalling the driver:
- Right-click your disk, select “Uninstall device,” then restart your PC. Windows will automatically reinstall the correct driver.
Method 3: Run Windows Hardware Troubleshooter
- Press
Windows + R, typemsdt.exe -id DeviceDiagnostic, then press Enter. - Follow the prompts to detect and fix hardware-related issues.
Method 3: Run Check Disk Utility (CHKDSK)
- Open Command Prompt as administrator.
- Type
chkdsk /f c:(replacec:with your affected drive letter) and press Enter. - Restart your computer to allow CHKDSK to run at startup.
Method 4: Update Your BIOS
- Visit your motherboard manufacturer’s website.
- Carefully follow the provided instructions to safely update your BIOS firmware.
Conclusion
Regular monitoring and proactive maintenance can help avoid recurring UDMA CRC errors. Ensure your hardware is connected properly, keep drivers updated, and maintain system firmware for optimal performance.
