    While trying to download a game or update an old game, you may encounter a corrupt disk error on your Steam client. This is a common error and can occur due to several reasons.

    The full error reads as follows:

    An error occurred while updating [your game] (disk read error) (disk corruption error), see the Steam support site for more information.

    For those affected by this error, here is how to fix the corrupt disk Steam error on your Windows machine.

    Why does Steam say corrupt download?

    Keep in mind that in case BSOD or power outage interrupted the Steam game downloading process, it might have corrupted your download files.

    Hence, you’ll probably get the corrupt update files error. If there are problems on your hard disk drive where you have installed Steam, it might result in this error.

    In case you’re wondering what exactly is a corrupt disk, do not forget that hard drive data corruption appears when a system cannot finish writing data to a file or when segments of the file become inaccessible.

    How do I fix the Steam Corrupt Disk download error?

    1. Delete the active download folder or rename it

    1.1 Delete the folder

  • Use the following keyboard shortcut to open File Explorer: Windows + E.
  • and navigate to the following location: C:\Program Files\Steam\Steamapps\Downloading
  • Steam stores every game with a unique number. Open the first folder you see inside the downloading folder with a number. Check if it belongs to the problematic game.
  • Delete the folder.
  • Exit Steam if still running. Relaunch Steam and try to install the game again.

    • Before moving to advanced troubleshooting, consider temporarily disabling the Firewall and antivirus. Try again, and if that doesn’t help, move to additional troubleshooting steps.

    Another reason for the corrupt disk error can be the corrupt game’s files. You can try to delete the game’s files that are downloading and then restart the download from the Steam client.

    1.2 Rename the folder

  • Locate the Downloading folder in Steamapps by navigating to the following path: C:\Program Files (x86)\Steam\Steamapps
  • Right-click on Downloading folder and select Rename. Rename the folder as Downloading12.
  • Next, create a new folder in the Steamapps folder and name it as Downloading.
  • Launch Steam and try to install the game that was giving the issue. You should be able to download and install the game now.

    • Rename the download folder to something else and create a new folder named downloading as shown in the steps above.
