Official Steam Troubleshooting

1. Restart Steam and Computer

Needless to say, restarting is always the first thing to try. Please restart Steam and then repeat the downloading/upgrading. If the Steam disk write error persists, restart your computer.

2. Clear Download Cache

Clearing the download cache of Steam will force the Steam client to flush locally cached configuration data and acquire it from the Steam server again.

Please follow this path to do the clean: Steam > Settings > Downloads > Clear Download Cache

3. Reinstall Steam

Reinstalling Steam may fix potential issues with Steam client and service files while preserving all installed games. Remember: DO NOT uninstall (this may delete all game content), just reinstall Steam to the same location.

4. Repair Library Folder

The Steam Library contains all your installed games which should be writable by all users so as to download or update properly. However, sometimes Steam game update stuck because the user permissions changed and need to be refreshed.

Please follow this path to do the repair: Steam > Settings > Downloads > Steam Library Folders > Right click on folder > Repair Folder

5. Verify Local Files

Bad hardware, software crashes, and power surges can corrupt the game folders. You can use Steam to verify the integrity of these files and fix them if necessary.

Find Game in Library > Right click on Properties > Local Files > Verify Integrity of Game Files

6. Change Download Region

The Steam content system is divided into geographical regions. The Steam client automatically detects its current region and uses content servers located in that region.

Sometimes, servers in a specific region may be slow or overloaded, leading to Steam disk write error while downloading. You can switch to a different download region, using another set of content servers to have a try.

Please go to Steam > Settings > Downloads > Download Region. You may need to test several regions other than your own.

7. Move Game Folder

It is worth trying to install the game on another hard drive in case it is the hard drive failure. If this works, you can then create a new Steam Library folder on this drive and install new games or move the already installed games into this Steam Library folder.

Please go to Steam > Settings > Downloads > Steam Library Folders > Add New Library Folder

8. Refresh Local Network Hardware

Network hardware can get into a slow/broken state after running for a long time. Restarting all modems & routers might be helpful to fix Steam disk write error.

9. Update System & Drivers

Make sure your operating system and hardware drivers are all up to date and repeat the downloading/upgrading.

For Windows: Start > Search “update” > Run “Check for Updates”

Windows check for update

For Mac: drivers cannot be updated separately; you can only update the operating system to the latest.

10. Investigate Firewalls

Certain firewalls may prevent Steam from talking to its servers. You can temporarily disable it for testing purpose. If that’s the reason, it may be necessary to add exceptions in your firewalls for Steam.

11. Investigate Anti-Virus

Anti-Virus hooks deep into the operating system and can affect disk and network operations, further leading to issues with Steam. Besides, some games use copy protection technology which may appear as malicious software to an antivirus scanner, resulting in Steam disk write error. You can completely disable the Anti-Virus and check if the disk write error stopped.

Tip: Investigating Firewalls and Anti-Virus is also useful if Windows Backup Stuck at Creating System Image.

12. Investigate Other Programs & Services

Software that modifies or monitors systems and disk or network activity can cause issues while downloading or running a game. These programs and services can run in the background and are typically associated with software like Anti-Virus, ad-blockers, web-optimizers, firewalls, system cleaners, etc.

You may work with a tech support specialist to ensure that these services & programs are not interfering with Steam. You may even need to temporarily disable them for testing purposes.

13. Disable Overclocking

Some users overclock their hardware to gain the best performance without accepting manufacturers’ recommended settings. This can cause memory and file corruption and should be disabled (usually you can do this in the computer BIOS).

14. Test Online Connection

Some Internet providers cache or compress online data to save bandwidth. This can cause issues with Steam. It is good to try connecting your PC to an entirely different network from a different service provider to fix disk write error Steam.

15. Check RAM for Errors

Memory errors can cause issues with the Steam installation process, as well as gameplay. You’ll want to work with a tech support specialist to investigate possible issues with your system memory.
