The Destiny 2 disk write error has been causing frustration and irritation for PC gamers of late. There have been reports of feet being stamped, fists being clenched, and cushions being aggressively plumped, as a result. If you are one of those unlucky enough to have been obliged to watch Homes Under the Hammer repeats instead of playing Destiny 2 because of this error, you're in luck. We've put together some advice, to hopefully get back where you belong, in the thick of the action. Here's what we know about fixing the Destiny 2 disk write error.

How To Fix Steam Disk Write Error For Destiny 2

There are a couple of potential remedies to the Destiny 2 disk write error. The first is a recommendation from Bungie themselves. They suggest the following:

Players receiving error "appmanifest_1085660.acf/Disk write error" on Steam can manually delete the files *.acf.tmp.save, located in <Steam install folder>\steamapps folder, as a temporary workaround.

Given that this is the recommendation from the game developer, it seems a sensible starting point. But if that doesn't work for you, the other suggestion that seems to have worked for a number of players is to check what's going on with your antivirus or firewall software. This is especially true if the error has come up when you've recently carried out an update. So add destiny2.exe to your safe list, and this will hopefully stop the disk write error from happening.

If this doesn't work, then there are some other, more general steps to try:

  • Give Steam administrator privileges.
  • Verify the integrity of the game files:
    • Load Steam.
    • From the Library section, right-click on the game and select Properties from the menu.
    • Select the Local files tab and click Verify integrity of game files...
    • Wait. It usually takes a few minutes to complete.
  • Clear the Steam download cache by going to Steam > Settings > Downloads > Clear Download Cache.

If none of these helps, then it's probably time to get in touch with Bungie, to see if they have any additional tips. You can find them @BungieHelp on Twitter. But is there anything else we know about this error?

Bungie has suggested that their fix is a temporary solution, which suggests that even they aren't entirely sure why this error is happening. But typically, the error seems to be caused most frequently by an overzealous antivirus or firewall. It may also be caused by corrupted files.

So give the suggestions we outlined above a try. They seem to have worked for a lot of other players, so hopefully you will also find yourself wielding the Light once more.
