How to Fix the Steam Corrupt Disk Error on Windows?

The Corrupt Disk error in Steam usually occurs when users are trying to download the game they have just purchased or to update a game already installed on their computers. It often appears if something interrupts the downloading process such as a BSOD or a power outage but it can often simply appear out of nowhere.

Steam Corrupt Disk Error

Steam games can’t be played unless all updates are installed, which makes this problem quite serious. However, you should be relieved to hear that the problem can be resolved by many different methods listed below. Make sure you follow the instructions carefully.

What Causes the Steam Corrupt Disk Error on Windows?

There are several things which might have gone wrong and caused this problem to appear. We have chosen the most common ones among users to help you find out about your scenario and the best way to resolve the problem. Check out the list below:

  • Corrupt download files – If your downloading process was interrupted by a BSOD, a power outage, or something similar, it’s quite possible that the file being downloaded went corrupt. In that case, it’s good to reset the files being downloaded and start again.
  • Hard drive problems – It’s quite possible that your hard drive has run into problems and you should check for errors using the built-in error-checking tool.
  • The hard drive is being turned on – There is an option to turn off the hard drive after some time of inactivity to save power and it’s possible that this caused the problem. Make sure you disable this setting.

Solution 1: Rename the Downloading Folder

This problem often occurs if a file being downloaded becomes corrupted all of a sudden due to various reasons such as system crashes or random computer shutdowns. If that is the case, the download can’t proceed beyond the corrupted file and the Corrupt Disk error message appears. Follow the steps below to restart all downloads by renaming the “downloading” folder.

  1. Navigate to your Steam installation folder. If you haven’t configured any changes during the process of installation regarding the required installation folder, it should be Local Disk >> Program Files or Local Disk >> Program Files (x86).
  2. However, if you have the Steam program’s shortcut on the desktop, you can simply right-click on it and choose the Open file location option from the context menu which will appear.

Solution 2: Clear Download Cache

The second method is similar to the first one but this one looks to clear download files which are no longer necessary and which won’t interrupt the downloading process. It’s not as effective as the first method but it has also helped plenty of users.

  1. Make sure you start the Steam client by double-clicking it on the Desktop or by searching for it with your Start menu open and clicking on the first result.
  2. Click the Steam option from the menu at the top of the client’s screen and choose Settings. In the Settings window make sure you navigate to the Downloads tab and check the bottom of the window for the Clear Download Cache.

  2. Click the Steam option at the top left part of the Steam client and choose Exit to exit Steam completely (don’t just click the x button at the top right corner). Reopen Steam, relaunch the download, and check to see if the Corrupt Disk error appears.

Solution 3: Run the Error Checking Utility

Running the Error Checking utility for the drive where your game is installed does wonders for this error message as it manages to fix file errors and resolve drive issues when it comes to file management. Resolving these errors for the drive where the game is located should resolve your problem immediately.

  1. Open your Libraries entry on your PC or open any folder on your computer and click on This PC option from the left side menu. If you are using an older version of Windows (Windows 7 and older), simply open My Computer from your Desktop.
  2. Right-click on the drive where your game is installed and choose the Properties option from the context menu which will appear.

Solution 4: Change Power Settings

The problem may be caused by hard disk problems when the HDD is turned off at the wrong moment, just enough to corrupt the file being downloaded. This causes the Corrupt Disk error and it prevents the file from downloading further. Try disabling the option to turn off the hard drive to save power in Power Options!

  1. Right-click on the battery icon located in the system tray and click on Power Options. If you are not using Windows 10, click on the Start menu and search for Control Panel. Change the View by option to Large icons and click on the Power Options.
