  • After that, you can attempt again to see if the disk write error occurs.

The next option is to restart your computer or the system on which Steam is installed. Restart your machine and close any applications that may be interfering with Steam.

  • Select the “Start” button.

Your antivirus program may be preventing you from writing files to your hard drive. You can always turn off your antivirus and try again to download the games. Adjust your antivirus settings and make a scan exception for Steam.

Change your firewall/antivirus settings at your own risk, as doing so can expose your PC to fraudulent, viral, or malicious attacks.

  • Turn off your antivirus software.
  • Disable your Firewall.
  • Check to see if the Steam Disk Write Error has been resolved.

If any files in your game installation are corrupt, you may run into this problem. Antivirus programs have also removed them as false positives. So you can check the game files for integrity to see if it resolves the issue.

  • Right-click the game that causes disk issues and select “Properties” from the “Library” tab.
  • The “Verify Integrity Of Game Files” button appears after clicking the “Local Files” tab. Simply press the button.
