CIM_LogicalDisk class
Represents a contiguous range of logical blocks that is identifiable by a file system through the disk's DeviceID (key) field. For example, in a Windows environment, the DeviceID field contains a drive letter; in a UNIX environment, it contains the access path; and in a NetWare environment, it contains the volume name.
The following syntax is simplified from Managed Object Format (MOF) code and includes all of the inherited properties.

The OperationalStatus property replaces the deprecated Status property. Due to the widespread use of the existing Status property in management applications, we strongly recommend that providers or instrumentation provide both the Status and OperationalStatus properties. When instrumented, Status, because it is a single-valued property, should also provide the primary status of the element.
This property is inherited from CIM_ManagedSystemElement.

Aborted (14)
Indicates that the job stopped in an unexpected way. The state and configuration of the job might require an update.
Dormant (15)
Indicates that the job is inactive.
Supporting Entity in Error (16)
Indicates that an element on which this job depends is in error. This element might be OK but cannot function because of the state of a dependent element. An example is a network service or endpoint that cannot function due to lower-layer networking problems.
Completed (17)
Indicates that the job has completed its operation. This value should be combined with either OK, Error, or Degraded to indicate to a client whether the complete operation Completed with OK and passed, or completed with Error and failed, or completed with Degraded and finished the operation, but did not complete OK or did not report an error.
