CIM_DVDDrive class
Represents the capabilities and management of a DVDDrive.
Important The DMTF (Distributed Management Task Force) CIM (Common Information Model) classes are the parent classes upon which WMI classes are built. WMI currently supports only the CIM 2.x version schemas.
The following syntax is simplified from Managed Object Format (MOF) code and includes all of the inherited properties.
