The Disk Driver service is a kernel device driver. In Windows 8 it is being loaded by Boot Loader before Kernel initialization. If Disk Driver fails to start, the error details are added to Windows 8 error log. When the operating system startup is complete, the user is being notified that the disk service hasn't been started.
