Default Behavior

Crcdisk Filter Driver is a kernel device driver. In Windows 7 it is disabled and therefore it isn't starting. If Crcdisk Filter Driver fails to start, Windows 7 attempts to write the failure details into Event Log. Then Windows 7 startup should proceed and the user should be notified that the crcdisk service is not running because of the error.

Restore Default Startup Configuration for Crcdisk Filter Driver

1. Select your Windows 7 edition and service pack, and then click Download.

2. Save the Win7_crcdisk_Service_Startup.cmd file to a local storage device.

3. Run the saved file as an administrator.

4. Restart the computer.

The crcdisk service is using the crcdisk.sys file that is located in the %WinDir%\system32\DRIVERS folder. If the file is changed, damaged or deleted, you can restore its original version from Windows 7 installation media.
