Fix the 'Steam Disk Write' Error

You can fix the Steam “Disk Write Error” message on your Windows desktop by following these workarounds:

1. Disable Write Protection for Steam

The “Disk Write Error” message generally appears when Steam tries to change or add files to a drive folder, but the Write protection is enabled. Since Write protection restricts Steam from making any changes to the files on your Drive, you will need to disable it by following these steps:

  • On the Steam Properties window, click the General tab and uncheck the ‘Read-only’ checkbox next to the ‘Attributes’ section.
  • Finally, click the ‘Apply’ button to save the changes and close the window.
  • Now try updating or installing the desired game to see if the disk write error is fixed.

2. Run Steam as an Administrator

Sometimes, Steam might need administrative rights to write files on your hard disk. In such cases, you will need to run the Steam app as an administrator, and you can do this by following these steps:

  • Right-click on the Steam app and select the ‘Properties’ option.
  • Click the ‘Compatibility’ tab on the Properties window and click the ‘Run this program as an administrator’ checkbox to tick it.
  • Finally, click the ‘Apply’ button to save the changes and close the window.
  • Now check if the error is fixed.

3. Clear Steam Download Cache

4. Other Methods to fix the Disk Write Error
