1. Delete the active download folder or rename it
1.1 Delete the folder

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.
