This guide aims to explain Steam Disk Write Error, its cause and its solution in a detailed and proper manner. It’s important to identify that by the end of this guide, you will be ready to fix the problem and game on.
What Is the Steam Disk Write Error?
The Steam Disk Write Error is usually brought forward when Steam cannot write new files or update files on your hard drive. This problem often arises whenever one is downloading a game or during an update of a game. The error message usually reads something like:
- “An error occurred while updating [game name] (disk write error).”
- “An error occurred while installing [game name] (disk write error).”
Both on Windows and on macOS, this error can occur, and it is most frequently connected to file permissions and hardware problems or corrupted game files.
Common Causes of Steam Disk Write Error:
Before diving into solutions, it’s essential to understand the most common reasons behind the Steam Disk Write Error:
- Write Protection on Disk: This will inhibit new data from being written by Steam if the drive where it is or the download location of the games is write-protected.
- Corrupt Files in Steam Library: Sometimes, corrupted game files or an error in downloading a game partially may lead to this error.
- Hard Drive Issues: Bad sectors or a failing hard drive can result in Steam having trouble when writing files, mainly because of the notorious Steam cache issues.
- Antivirus or Firewall Interference: Excessive measures by security programs can prevent Steam from writing files or updating games.
- Insufficient Permissions: Steam may not have the administrative permissions to edit/write files on your files or modify them in any way.
- Download Cache Issues: The write error could be originating from the download cache which has become corrupted.
How to Fix Steam Disk Write Error
Since you already know the causes, allow me to take you through some step-by-step ways to deal with the Steam Disk Write Error. The above solutions should be implemented singly since the body may react differently to each remedy.
1. Restart Steam and Your PC
For many software-related problems, a reboot will be the first solution given by most technicians. Restart Steam and your computer to fix the issues that could stem from a freezing or a glitch. This method is helpful, provided the problem is a result of the fact that Steam did not successfully finish a previous download or installation.
2. Remove Disk Write Protection
To ensure the drive Steam is writing to isn’t write-protected, follow these steps:
- For Windows:
- Press Win + R, type diskpart, and hit Enter.
- In the command prompt, type list disk and press Enter.
- Select the drive by typing select disk X (replace X with your drive number).
- Type attributes disk clear read-only and press Enter.
- Restart your PC and try installing or updating the game again.
3. Run Steam as an Administrator
Generally, there might be no permission for Steam to write on protected directories. Running it as an administrator can fix this:
- Open a folder with Steam in it, then right-click the icon that says Steam and click on “Run As Administrator”.
- This ensures that Steam is provided with the access rights to make or change files on your disk.
4. Clear the Download
Broken download caches are a common reason for the appearance of disk write errors. Here’s how to clear them:
- Open the Steam and select settings from the displayed list.
- Click on Clear Download Cache which is under the Downloads tab.
- Make sure about the action done for the registry and restart the Steam again.
This will clear all the caching files that may be hindering the downloading of files.
5. Verify Game Files Integrity
If the issue is limited to a specific game, verifying the integrity of the game files can fix the problem:
- Open Steam and go to the Library.
- Go to the properties of the game where you are seeing the particular error on the right-click option.
- The last thing you need to do is go to the Local Files tab and then click on the button labelled Verify Integrity of Game Files.
Steam will then go through all the files of the game and patch any damaged or even entirely missing data.
6. Check the Hard Drive for Errors
If there are bad sectors then it could likely be your hard drive. Running a disk check can resolve the issue:
For Windows:
- Go to the Windows Explorer, separately click on your Steam drive and select properties.
- Go to the toolbar, select Tool, and then Check under the last option Error-check”.
- As indicated here in the steps, the user can scan for and repair disk errors, as illustrated below.
For macOS:
Then, insert the disk, go to Disk Utility, find the drive and click on First Aid to check or repair the disk.
7. Disable Antivirus or Firewall
Antivirus or firewall may interfere with the writing of files in Steam, which may affect the disk writing process significantly. Disable your antivirus for a while and see whether it works or not, or even turn your firewall off completely.
For Windows Defender:
- Go to Settings > Update & Security > Windows Security.
- Select Virus & Threat Protection and temporarily turn off real-time protection.
If this solves the issue, it is advised to add Steam as an exception to the antivirus or firewall programs that are being run on your PC.
8. Move the Game to a Different Drive
If your primary drive is causing issues, consider moving the game installation to a different drive:
- Go to Steam > Settings > Downloads.
- Under Content Libraries, click Steam Library Folders.
- Add a new folder on a different drive and reinstall the game there.
