How do I fix disk write errors for DotA 2 on Windows 10?

  4. Update your drivers
  5. Install DotA 2 on another drive

Sometimes, file system errors can lead to Steam and DotA 2 problems.

However, if the problem persists and you’re sure that disk issues are to blame, you could also consider the use of a more powerful solution, and that is using a third-party tool like Restoro.

Besides being a generic Registry and DLL fixes, Restoro can easily handle disk errors as well, even those that Windows 10 itself cannot handle without a full CHKDSK or a SFC scan.

2. Disable your antivirus’ firewall

Some users reported that they are also experiencing this particular DotA 2 error due to their firewall interfering. so another solution that you should try is to either disable the Windows 10 Firewall, or that of your antivirus.

While this could potentially fix the issue, you will be left exposed without a firewall to protect you, especially if you forget to turn it back on after you’re done playing.

So, instead of disabling your firewall, consider switching to an antivirus tool that has better firewall flexibility, or at least one that is easier to turn off and back on again.

3. Verify the integrity of the game cache

  1. Open your Steam Client > go to Library.
  2. Right-click on DotA 2 and select Properties.
  3. Under Local Files > choose Verify integrity of game cache…dota 2 steam update disk write error windows 10

4. Update your drivers

Outdated drivers have also been commonly associated with disk write errors, especially if the ones powering your HDD are incredibly old, or possibly even never updated.
