MSFT_MTDisk class
The disk drive data object. Statistic data is calculated based on current interval seconds setting.
The following syntax is simplified from Managed Object Format (MOF) code and includes all of the inherited properties.

Properties
The MSFT_MTDisk class has these properties.
-
ActiveTime
-
-
Data type: real32 array
-
Access type: Read-only
Gets a list of percentage of active time accessing to and from the disk drive.
-
-
AverageResponseTime
-
-
Data type: real32
-
Access type: Read-only
Gets the average response time during latest sampling interval on the disk drive, in milliseconds.
-
-
Capacity
-
-
Data type: uint64
-
Access type: Read-only
Gets the capacity of the disk drive.
-
-
Caption
-
-
Data type: string
-
Access type: Read-only
-
Qualifiers: MaxLen (64)
The Caption property is a short textual description (one- line string) of the object.
This property is inherited from CIM_ManagedElement.
-
-
CurrentIndex
-
-
Data type: uint16
-
Access type: Read-only
Gets the current data sample index. Increment at every data sample.
-
-
Description
-
-
Data type: string
-
Access type: Read-only
The Description property provides a textual description of the object.
This property is inherited from CIM_ManagedElement.
-
-
DiskNumber
-
-
Data type: uint32
-
Access type: Read-only
Gets the index number of storage disk device for the disk drive. It is not guaranteed to be persistent across boots.
-
-
ElementName
-
-
Data type: string
-
Access type: Read-only
Gets a user-friendly name for the object. This property allows each instance to define a user-friendly name in addition to its key properties, identity data, and description information. Note that the Name property of CIM_ManagedSystemElement is also defined as a user-friendly name. But, it is often subclassed to be a Key. It is not reasonable that the same property can convey both identity and a user-friendly name, without inconsistencies. Where Name exists and is not a Key (such as for instances of CIM_LogicalDevice), the same information can be present in both the Name and ElementName properties. Note that if there is an associated instance of CIM_EnabledLogicalElementCapabilities, restrictions on this properties may exist as defined in ElementNameMask and MaxElementNameLen properties defined in that class.
This property is inherited from CIM_ManagedElement.

-
InstanceID
-
-
Data type: string
-
Access type: Read-only
InstanceID is an optional property that may be used to opaquely and uniquely identify an instance of this class within the scope of the instantiating Namespace. Various subclasses of this class may override this property to make it required, or a key. Such subclasses may also modify the preferred algorithms for ensuring uniqueness that are defined below. To ensure uniqueness within the NameSpace, the value of InstanceID should be constructed using the following "preferred" algorithm: "OrgID:LocalID" Where OrgID and LocalID are separated by a colon (:), and where OrgID must include a copyrighted, trademarked, or otherwise unique name that is owned by the business entity that is creating or defining the InstanceID or that is a registered ID assigned to the business entity by a recognized global authority. (This requirement is similar to the <Schema Name>_<Class Name> structure of Schema class names.) In addition, to ensure uniqueness, OrgID must not contain a colon (:). When using this algorithm, the first colon to appear in InstanceID must appear between OrgID and LocalID. LocalID is chosen by the business entity and should not be reused to identify different underlying (real-world) elements. If not null and the above "preferred" algorithm is not used, the defining entity must assure that the resulting InstanceID is not reused across any InstanceIDs produced by this or other providers for the NameSpace of this instance. If not set to null for DMTF-defined instances, the "preferred" algorithm must be used with the OrgID set to "CIM".
This property is inherited from CIM_ManagedElement.
-
-
IntervalSeconds
-
-
Data type: uint16
-
Access type: Read-only
Gets the current data collection interval in seconds.
-
-
Name
-
-
Data type: string
-
Access type: Read-only
-
Qualifiers: key
Gets the name of disk drive.
-
-
ReadTransferRate
-
-
Data type: real32 array
-
Access type: Read-only
Gets a list of historical statistics of average disk read transfer rate, in byte, per second, logging latest 60 samples at each interval defined in IntervalSeconds (second).
-
-
Volumes
-
-
Data type: MSFT_MTDiskVolume array
-
Access type: Read-only
-
Qualifiers: EmbeddedInstance ("MSFT_MTDiskVolume")
Gets an array of MSFT_MTDiskVolume objects containing disk volumes configured on the disk drive.
-
-
WriteTransferRate
-
-
Data type: real32 array
-
Access type: Read-only
Gets a list of historical statistics of average disk write transfer rate, in byte, per second, logging latest 60 samples at each interval defined in IntervalSeconds (second).
