The Win32_DiskDrive class represents a physical disk drive as seen by a computer running the Win32 operating system. Any interface to a Win32 physical disk drive is a descendent (or member) of this class. The features of the disk drive seen through this object correspond to the logical and management characteristics of the drive. In some cases, this may not reflect the actual physical characteristics of the device. Any object based on another logical device would not be a member of this class.
Example: IDE Fixed Disk.
