How To Fix Steam Disk Write Error Easily

Steam Disk Write Error is a standard error that often confuses users. Crashes manifest as messages when you try to download/install / update/run the game. The Steam Disk Write Error may be due to write protection, physical defects, antivirus activity, or other problems. Below are the main methods that allow you to restore the software’s functionality on your own.

Restart the app and PC

The first thing to do if Steam is not writing to disk is to restart the computer/laptop and the application. Such actions save a situation if the problem is temporary and caused by minor malfunctions in the system. First, restart Steam, and if that doesn’t help, do the same action from the PC. If there is no result, go to the next step.

Remove write protection

An error when writing to a Steam disk can be caused by protection from performing such actions. As a result, it is physically impossible to add or change files to a folder or the entire disk on a computer or laptop. If there is protection, an inscription appears, and an error occurs writing to the Steam disk. To fix the problem, remove the write protection from the drive where the game of interest is stored.

Run the program as an administrator

When looking for ways out of this situation, you cannot dismiss the most straightforward way – running Steam as an administrator. The method helps out in a situation where the application, for some reason, lacks the necessary permissions. In many cases, the error when writing to the Steam disk disappears if you give the application extended rights.

Turn off the “Read Only” setting

Using the Windows operating system on a PC or laptop allows you to use the “Read Only” option. This option can be enabled for individual files or folders. If you see an error writing to a disk in Steam, pay attention to what permission is set on the directory. If you have the “Read Only” option, this will inevitably cause program crashes. To solve the problem, do the following:

  • Find the Steam folder.
  • Click on it with the right mouse button.
  • Turn off Read Only.

After that, rerun the application and check whether the specified method worked.

Remove corrupted files

When looking for answers to the question of what to do if a disk writing error occurs on Steam, try to remove the corrupted items. Steam automatically uploads the incorrect file when there are difficulties during the download. As a result, there are failures in the launch of the application. To resolve the situation, do the following:

  • Enter the Steam directory.
  • Navigate to the Steamapps folder.
  • Sign in Common.
  • Find a file with the same name as the name of the game you are trying to run.

Check the document size. The worst option is the appearance of an indicator of 0 kB, which means that this particular file causes the disk write error in Steam. Delete it and try relaunching the game.

Do not be afraid to delete corrupted files because the next time you log in, the system should load them automatically. The problem could also be fixed in manual mode. If an error occurred while writing to the Steam disk during the update. To do this, do the following:

  • Log in to Steam and look for the game you need to update or run.
  • Right-click and select Properties.
  • Go to Local Files and click Verify Integrity of Game Files.

After the steps have been completed, Steam checks the files, and if there is damage, it downloads new ones at the next start. Remember, if the game uses a launcher and downloads additional updates, do not check the integrity of the files. In this case, the updated game will be replaced with a standard launcher, and you will have to download the updates again.

Change folder security

A common reason Steam is not writing to a disk is incorrect writing and reading settings. As a result, an error occurs when loading. To correct the situation, take the following steps:

  • Log into the drive where Steam is installed.
  • Click on the folder with the right mouse button.
  • Select Properties.
  • Enter the Security section.
  • Select each user under Groups or Users.
  • Pay attention to the presence of a ban on writing and reading.

If a ban is found, click on Edit and remove the restriction. After that, right-click on the Steam folder again and go to Properties. There, find Attributes and uncheck Read Only (if you didn’t already).

Clear the cache

Many users recommend clearing the cache when asked what to do if it says “Error writing to disk” in Steam. This action helps to save the situation if the cache is corrupted or takes up too much RAM space. The algorithm of activities is as follows:

  • Sign in to Steam.
  • Go to the View category at the top left and the Settings.
  • Go to Downloads and click Clear Download Cache.

Confirm the actions and check if the error of writing to the Steam disk is gone or not. If there is no result, go to the next step.

Change download region

An excellent way to fix the problem is to change the server region for downloading. As a rule, the program determines it automatically, but sometimes this process fails. Alternatively, the correct server may be overloaded, causing errors. To solve the problem, do the following:

  • Go to Steam.
  • Go to the View tab and then Settings.
  • Go to Downloads and select a different region.

After that, save the settings, restart the application, and check if the previous error is gone.

Move Steam to another drive

The situation is more complicated when the installation encounters an error writing to the Steam disk. Moving the program to a disk with more space can help in this case. If there is insufficient space on the primary drive, a write error occurs. If such a step helps solve the problem, this is evidence of problems with the element for storing information. Do not leave the situation to chance because, in the future, other issues may arise with this.

Check disk space for errors.

One of the reasons why a disk write error occurred in Steam is problems with disk space. To solve the problem, check the product for possible issues. In addition, such checks are helpful when several partitions are on the same disk or when moving the Steam folder does not work. If the problem with disk space errors reoccurs in the future, the HDD may need to be replaced.

Disable antivirus/firewall or add software to exceptions

An error writing to Steam may indicate the operation of an antivirus program or a firewall. The reason is that some software identifies Steam as malware and blocks it. If the previous steps did not fix the error, try temporarily disabling your antivirus while downloading the application. If there is a result, add Steam to the exceptions.

The same rule applies to the firewall (firewall), which can also block Steam from working. As in the previous case, try temporarily disabling the blocking software and check if the recording error appears. If not, add Steam to the exceptions and quietly work on it.

Reset configuration to default

In many cases, resetting the Steam configuration to its original default settings can save. To do this, press the Win + R combination and enter the steam://flushconfig command. Once you’ve completed the steps, make sure they work.

Prevent DEP Data Execution

If a Steam disk writing error occurs, preventing the execution of DEP data can help. To solve this problem, do the following:

  • Click on the combination of buttons Win + R.
  • Write the sysdm.cpl command to open the system properties.
  • Go to the Advanced section.
  • On the Performance tab, click Options.
  • In the new tab, click on Data Execution Prevention.

Make sure the feature is enabled. If it is disabled, click Add and specify the path to the Steam executable file (steam.exe).


The above steps will most likely help you with the Steam disk write error. You can always contact the community for advice and report to the support service if there is no result. But when following the steps discussed in the article is unnecessary. Use also if you need any drivers on your PC.
