“Windows7_OS (C:) (Missing)” and “Windows7_OS (C:) (System)” are displayed on the ”System Protection” tab after restoring the hard disk drive to the factory default state

Symptom

After restoring the hard disk drive to the factory default state on the Microsoft Windows 7 operating system, two C drives are displayed as available drives in the "Protection Settings" area on the "System Protection" tab in the System Properties window.
