MSFT_SMDiskDrive class

  • [アーティクル]

Represents a disk device. The disk may be directly attached to the computer system, or it may be a virtual disk exposed to the system through the use of a Storage Management Provider.

The following syntax is simplified from Managed Object Format (MOF) code and includes all of the inherited properties.

Windows Server 2012 R2 and Windows Server 2012: This class does not inherit from MSFT_SMStorageObject which is new for Windows Server 2016.
