Troubleshooting Category 4: Windows Troubleshooting

It seems nothing is wrong with your Steam client, so we recommend you begin troubleshooting basic Windows errors.

Method 1: Disable Overclocking

Some users try to overclock their PCs to utilize them to their maximum capacity. However, this also has some negative effects, like Steam Disk Write Error. Experts suggest disabling overclocking and then rebooting your PC.

Method 2: Update Drivers

Another important troubleshooting method is to update the drivers and fix the disk write error when updating and installing game issues. You can update the drivers manually using the Device Manager. However, we prefer the automatic driver updater software, known as Advanced Driver Updater. Here are the steps to identify and replace corrupt, missing, and outdated drivers with updated ones.

Step 1: Download and install Advanced Driver Updater using the download button below.

Step 2: Open the app and click the Start Scan Now button. A list of driver anomalies will appear on the screen.

Method 3: Disable Your Antivirus Program

There have been reports in the tech forums that certain antivirus software does not allow Steam to write files or make changes on the hard disk. Hence, we will have to temporarily disable the antivirus and check if this error occurs because of the antivirus software.

Method 4: Check Your Firewall

Windows Firewall is another software that ensures your PC is safe and secure. The firewall may be blocking Steam from running. Hence, you should try adding Steam to the safe list or temporarily disabling it.

Step 1: Press the Win key and type Control Panel.

When Steam tries to save a file to your hard disk, it may generate the Disk Write Error. Therefore, we need to run a check disk scan on your hard disk to check it for errors. The Check Disk is a built-in tool for bad sectors on the hard drive. Here are the steps:

Step 1: Press Win + S to open the Windows Search box and type Command Prompt.
Step 2: Click on Run As Administrator and type the following command.
Step 3: Type the following command and press the Enter key.
