Checking Hard Drive Health

Hitting a Steam Disk Write Error can be rather annoying. One frequent culprit is problems with your hard drive. However, checking the hard drive’s health can pinpoint and resolve such issues. In this section, we will take you through checking your hard drive health using native tools and third-party software.
Using Built-in Tools
Most operating systems have built-in utilities for checking the health of your hard drive. These tools are easy to use. The native CHKDSK utility is one of the popular choices for Windows users. Launch Command Prompt with Admin access. Then type chkdsk /f and press Enter. This will scan for and repair errors on your hard drive. MacOS users will have to use the Disk Utility tool. It’s just a matter of opening the Disk Utility app, selecting your hard drive, and clicking “First Aid”. This will test for and repair any issues with the disk.

Install the software by downloading it. Run a health check on your hard drive. These programs will scan you for potential issues. Regular checks can prevent mistakes in the future.
Adjusting Permissions
Changed PermissionsSteam Disk Write Error Solution. Permissions control the ability to read, write, and execute files. Steam may be unable to update or install games properly due to incorrect permissions. Two approaches helped: running as an administrator and changing folder permissions.
Running As Administrator

A common workaround for permissions errors is to run Steam as an administrator. Running an application as an administrator grants access to elevated privileges, enabling it to complete tasks that may be limited with a standard user account.
Using Steam as an Administrator: Right-click the Steam shortcut on the desktop. Click Run as administrator from the context menu. A prompt may pop up asking for permission; click “yes.”
This basic action can occasionally fix the disk write error on the spot. Have you tried this before? If not, try it and see if it helps.
Modifying Folder Permissions
If you still encounter issues even after running Steam as an administrator, the next solution would be to change folder permissions. The Steam installation folder should have full access (Read/Write/Execute).
Find your Steam installation folder first. Typically, it will be under C:\Program Files (x86)\Steam. Then click Properties on that folder after right-clicking on it.
Switch to the Security tab within the Properties window. Click the “Edit” button. In here, ensure your user account has complete control. If not, click your user account and tick the ”Full control” box. Click “Apply” and then “OK”.
Modifying these permissions gives Steam the appropriate rights to modify files. This is especially useful when facing recurrent write errors.
Have you ever encountered folder permission problems? If yes, how long did it take you to resolve them? Consider sharing your experiences so people experiencing this know they are not alone.
Disable Antivirus Temporarily

For many gamers, the dreaded Disk Write Error is one problem that crops up while using Steam . Antivirus software is a surprising cause of this error. You can determine whether or not your antivirus is the cause by temporarily disabling it. Now, let’s jump into how to do this effectively and safely.
Antivirus Exceptions
Antivirus software can sometimes detect Steam as something it shouldn’t be. This will keep Steam from writing to your disk, resulting in the Disk Write Error. You can add Steam as an exception in your antivirus software to fix this issue.
Look for an ‘Exceptions’ or ’Exclusions’ section in your antivirus settings. Make sure to add the Steam folder to this list. This instructs your antivirus to leave Steam alone.
The process is likely to fix the error without permanently disabling the antivirus. This is a less invasive way of doing things, and much better for your system’s security.
Temporarily Turning Off
If adding exclusions doesn’t help, you may have to disable your antivirus temporarily. This is a fast troubleshooting step to make sure that your antivirus isn’t the culprit.
Most antivirus solutions also allow you to temporarily turn off protection. Try options such as Disable Protection/ Turn Off Antivirus. Choose the shortest time window available, such as 10 or 15 minutes.
Disable and then try running Steam again. If you are able to resolve the Disk Write Error, you will then know what your cause is. Just remember to re-enable your antivirus after testing.
Have you ever thought why your antivirus would block Steam in the first place? It’s typically the result of how Steam downloads and updates games, which can look suspicious to protective software.
These steps will allow you to fix the Disk Write Error easily without putting your computer’s safety at risk. Have you experienced this problem earlier? How did you resolve it?
