- Open Command Prompt as Administrator
- Run this command:
sfc /scannow - Allow the scan to finish. Afterwards, execute:
DISM /Online /Cleanup-Image /RestoreHealth
These tools will repair corrupted system files using cached or downloaded content from Windows Update.
5. Check Disk for Bad Sectors
Faulty sectors on a hard drive can prevent file access and produce this error:
- Open Command Prompt as Administrator
- Enter:
chkdsk C: /f /r - Press Y if prompted to run on next restart
- Restart PC to let CHKDSK run and repair disk issues
6. Update or Reinstall Device Drivers

- Press Windows + X and select Device Manager
- Expand the category (e.g., Disk Drives or Universal Serial Bus)
- Right-click and choose Update driver
- Choose Search automatically to find updated drivers
If updating doesn’t help, uninstall and reinstall the driver instead.
7. Disable Antivirus Temporarily
Occasionally, third-party antivirus software interferes with disk operations. As a test, disable your antivirus temporarily and repeat the operation that triggered the error. If it works, consider switching to a different antivirus program or adjusting its settings.
