Solution Steps
- 1 Press Windows key + X and select Windows Terminal (Admin). Type 'chkdsk C: /f /r' and press Enter. You'll be prompted to schedule it for next reboot. Restart your PC. This checks your drive for file system errors and bad sectors. It's like a doctor scanning your drive for issues.
- 2 After the scan, open Device Manager (Win+X → Device Manager). Expand Disk drives, right-click your SSD/HDD, and select Update driver. Choose 'Search automatically for drivers'. If Windows doesn't find a new driver, visit your drive manufacturer's website (Samsung, Intel, WD, etc.) to download the latest firmware and driver. Outdated firmware can cause this error.
- 3 Press Windows key + R, type 'cmd' and press Ctrl+Shift+Enter to open Command Prompt as admin. Run 'sfc /scannow' to repair system files. Then run 'DISM /Online /Cleanup-Image /RestoreHealth' to fix the system image. Corrupted system files can affect the storage stack.
- 4 Check the health of your drive using a tool like CrystalDiskInfo. If it shows 'Caution' or 'Bad', your drive may be failing. Back up your data immediately and consider replacing the drive. This is critical to prevent data loss.
- 5 Press Windows key + I to open Settings → System → Recovery → Advanced startup → Restart now. Choose Troubleshoot → Advanced options → Startup Settings → Restart. Press 4 to boot into Safe Mode. In Safe Mode, run 'chkdsk C: /f /r' again. This can fix issues that are locked during normal boot.
- 6 If the error persists, open Device Manager and uninstall the storage controller under 'Storage controllers'. Restart your PC. Windows will reinstall the driver automatically. This resets the storage driver stack.

- Press Windows key + X and select 'Windows Terminal (Admin)' or 'Command Prompt (Admin)'. Run 'chkdsk C: /f /r' and press Enter. You'll be prompted to schedule it for next restart; type Y and restart. This checks your drive for file system errors and bad sectors. It's like a doctor scanning your drive for physical damage.
- After restart, run 'sfc /scannow' in the same admin terminal. This repairs corrupted system files that might be causing the error. Wait for it to complete.
- Update your storage drivers. Press Windows key + X and select 'Device Manager'. Expand 'Disk drives', right-click your drive, and select 'Update driver'. Choose 'Search automatically for drivers'. If no update is found, visit your drive manufacturer's website for the latest driver.
- Check drive health using a tool like CrystalDiskInfo. Download and run it. Look for 'Caution' or 'Bad' health status. If your drive is failing, back up data immediately and replace the drive.
- If the error persists, disable write caching on the drive. In Device Manager, right-click your drive, select 'Properties', go to 'Policies' tab, and uncheck 'Enable write caching on the device'. Click OK. This can prevent data corruption but may reduce performance.
- Perform a clean boot to rule out software conflicts. Press Windows key + R, type 'msconfig', and press Enter. Go to 'Services' tab, check 'Hide all Microsoft services', then click 'Disable all'. Go to 'Startup' tab and click 'Open Task Manager'. Disable all startup items. Restart. If the error stops, enable services one by one to find the culprit.
