Fortunately, there are several simple solutions to this unpleasant problem. We’ve investigated the issue and are now providing you with possible solutions to get you up and running as quickly as possible.
Without further ado, let’s jump right in.
Suggested Solutions for Steam Disk Write Error on Only One Game
It’s frustrating to receive a “disk write error” message while downloading or updating your favorite game. All you want to do is start the game as soon as possible, but this issue won’t allow that. Fortunately, there is a range of suggested solutions to help you pick up where you left off.
1. Restart Steam
The first and most simple remedy you can try is to restart your Steam client. Close and reopen the platform and download the game again.
2. Restart your computer
The next possible solution is to restart your computer or the system you use Steam on. Restart your PC and close any running programs that may be interfering with Steam.
3. Remove Disk Write Protection
If restarting Steam or your PC didn’t help, your drive may have write protection that prevents your PC from changing folders on that drive or adding new files to folders. Go to the drive where your Steam games are stored and remove their write protection. Follow these steps.
- Right click on the Steam folder within the directory (most likely in “C:/Program Files (86x)”) and click Properties.
- Find the attributes section under the General tab and make sure Read only is not marked.
- Click Okay to save changes.
- Restart Steam on your PC and try downloading the game again.
4. Run Steam as an administrator
There may be times when the software does not have permission to write files to your hard drive, causing the disc writing error. Fortunately, accessing the program as an administrator can help.
As an administrator, you have additional rights when running the software. Changing to this setting can also solve several other problems.
To start Steam as an administrator:
- Locate Steam on your desktop, right click on the icon and select Properties from the menu.
- Navigate to the Compatibility tab.
- Make sure the Run this program as administrator section is checked.
- Touch Okay to save changes.
Now you can restart the app and try to download the game again.
5. Delete Corrupted Files
If something goes wrong while downloading the game, it could be due to a corrupted file causing Steam to show the disc write error. To resolve the issue, follow these steps:
- Open the main Steam folder.
- Go to the “steamapps/common” folder.
- Look for the 0 KB files with the same name as the game you are trying to download.
- If these files are present, delete them and then launch or download the game again.

The most basic solution to fix Steam issues is to restart the software. Chances are, there’s a temporary problem downloading (or updating) the game and rebooting the platform might be all that’s needed to fix the problem.
2. Restart the PC
It’s a simple solution that usually seems to fix the problem: restart your PC. Make sure to close any programs that may be interfering with Steam and restart your computer. Try downloading the game again after it reboots.
3. Remove Disk Write Protection
The drive you installed Steam on may have write protection. This setting prevents apps from adding or modifying files stored on that drive. Make sure to check the drive where your Steam games are stored and remove the write protection.
Follow the instructions shown earlier to remove the write protection from the drive.
4. Turn off the Read-only setting
Your Steam folder may be set to read-only, meaning the entire folder is protected from file changes. Look for the read-only setting in Steam properties and make sure it is unchecked. As shown in the section above.
5. Check the integrity of game files
- Open your Steam library.
- Right click on the game and go to Properties.
- Navigate to Local files and click Check the integrity of game files.
- All copies of damaged files are replaced.
Remark: Do not attempt this step if your game uses a launcher to download additional updates. This action will replace the game update with the base launcher and you will have to download the updates again.
6. Clear the cache files
You can always try to clean the Steam cache files. It could be that one of them is corrupted and causing the disk write error. Here’s how to fix the problem:
- Launch Steam and go to Settings.
- Navigate to Downloads.
- click on Clear download cache.
7. Move Steam
If Steam is currently stored under drive C on your PC, you can try moving it to D or vice versa. There may be a problem with the drive that prevents Steam from manipulating files.
Remark: If this step helps to solve the problem, check the drive again to locate the problem.
8. Disable your antivirus
There may be a situation where your antivirus protection prevents the software from writing files to your disk. You can always disable your antivirus and try downloading the games again. If the error disappears, adjust your antivirus settings and add an exception for Steam during scans.
9. Disable the firewall
Try disabling your firewall or adding exceptions for Steam. If the issue is resolved, add an exception to your Windows Firewall.
Suggested Solutions for Steam Disk Write Error Appmanifest
As you browse your Steam folder, you will notice some “appmanifest” files in SteamSteamApps. These may look like random numbers, but are actually the game’s app numbers. These files let the app know where the games are installed.
But the numbers can be damaged and the path to the game becomes incorrect. To fix this, you can delete the appmanifest file or open the file in a text editor and type the absolute path of the game.
Remark: If you delete the file, it will appear that the game is not installed when you restart Steam. You have to download the game again.
Suggested Solutions for Steam Disk Write Error with an External Hard Drive
Your PC may write protect the hard drive, which may cause the write error. If your external hard drive is write protected, you can only access the files on it and you cannot make changes to the existing ones. Try removing the write protection to resolve this issue.
