Win32_CDROMDrive class
The Win32_CDROMDrive WMI class represents a CD-ROM drive on a computer system running Windows. Be aware that the name of the drive does not correspond to the logical drive letter assigned to the device.
The following syntax is simplified from Managed Object Format (MOF) code and includes all of the inherited properties. Properties are listed in alphabetic order, not MOF order.
