How to Fix Disk Write Error on Steam for Space Marine 2: Comprehensive Solutions and Tips

Warhammer 40K: Space Marine 2 faces several client-side multiplayer bugs, with many players encountering a peculiar error known as the Disk Write Error. This error often presents itself with a message like, “An error occurred while updating Space Marine 2: X:\SteamLibrary\steamapps\common\SpaceMarine2.”

This error typically arises when Steam cannot save game data onto your hard drive or SSD. It can be due to various reasons, including corrupted files, insufficient permissions, firewall interference, a malfunctioning hard drive, or Read-Only mode settings on the folder designated for the game installation.

1. How to Fix the Disk Write Error in Warhammer 40K: Space Marine 2?

The Disk Write error can be resolved using the following methods:

Restart Steam and Your PC
Verify Integrity of Game Files
Check Your Hard Drive for Errors
Check for Write Protection on Disk
Temporarily Disable Antivirus and Firewall

Sometimes, an improper configuration of Steam could lead to this error. A simple restart of Steam and, in some cases, your PC, may swiftly rectify the problem.

2. Restart Steam and Your PC

Merely closing the Steam window doesn’t fully terminate the application. To properly restart Steam, follow these steps:

Completely Close Steam.
To ensure it’s not running in the background, open Task Manager (by pressing Ctrl + Alt + Del) and verify the Steam process.
Relaunch Steam and attempt to install or update Space Marine 2 again.

If this method doesn’t resolve the issue, try rebooting your PC to refresh the operating system and then repeat the process.

3. Verify the Integrity of Game Files on Steam

Launch Steam.
Right-click on the “Warhammer 40K: Space Marine 2” icon in your Steam Library.
Select “Properties” from the drop-down menu.
Go to the Local Files tab, and
Click the “Verify integrity of game files” button.

Wait for the verification process to complete, and then relaunch the game.

4. Check Your Hard Drive for Errors

This fix will require a bit more effort. To check your hard drive:

Open File Explorer
Right-click on the drive where the game is installed.
Select Properties, then navigate to the Tools tab.
Under the Error-checking section, click ‘Check’ and follow the on-screen instructions to scan and repair errors.
Once the scan is completed, relaunch the game.

If this method doesn’t work, you may need to check the hard drive for proper permissions and protection to ensure that Steam can save games correctly.

5. Check Disk for Write Protection

To check for write permission, do the following:

Open File Explorer and go to the drive or folder where Space Marine 2 is intended to be installed.
Right-click on the drive/folder and select Properties.
In the General tab, ensure the “Read-only” checkbox is unchecked.
Click Apply after unchecking if it was checked.
Retry the installation on Steam.

This method usually resolves the error. If it doesn’t, unfortunately, there may be limited options aside from reaching out to Steam support. However, there are still a couple of minor fixes worth trying.

6. Temporarily Disable Antivirus and Firewall

Your antivirus software may block certain permissions or delete game files it deems potentially harmful.

To circumvent this issue, you should temporarily disable your antivirus. Each antivirus program has different steps for deactivation. Once disabled, restart your PC and relaunch the game.
