Win32_IDEControllerDevice class

  • Article

The Win32_IDEControllerDevice association WMI class relates an Integrated Drive Electronics (IDE) controller and the logical device connected to, for example, a disk drive.

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.

Properties

The Win32_IDEControllerDevice class has these properties.

AccessState

Data type: uint16

Access type: Read-only

Indicates whether the controller is actively commanding or accessing the device. This information is necessary when a logical device can be commanded by, or accessed through, multiple controllers.

This property is inherited from CIM_ControlledBy.

Unknown (0)

Active (1)

Inactive (2)

Antecedent

Data type: Win32_IDEController

Access type: Read-only

Qualifiers: Key, Override ("Antecedent"), MappingStrings ("CIM|Win32_IDEController")

A Win32_IDEController that represents the IDE controller associated with this device.

Dependent

Data type: CIM_LogicalDevice

Access type: Read-only

Qualifiers: Key, Override ("Dependent"), MappingStrings ("CIM|CIM_LogicalDevice")

A CIM_LogicalDevice that represents the logical device connected to the IDE controller.

NegotiatedDataWidth

Data type: uint32

Access type: Read-only

Qualifiers: Units ("bits")

When several bus or connection-data widths are possible, this property defines the one in use between the devices. Data width is specified in bits. If data width is not negotiated, or if this information is not available or important to device management, the property should be set to 0 (zero).

This property is inherited from CIM_DeviceConnection.

NegotiatedSpeed

Data type: uint64

Access type: Read-only

Qualifiers: Units ("bits per second")

When several bus or connection speeds are possible, this property defines the one being used between the devices. Speed is specified in bits-per-second. If connection or bus speeds are not negotiated, or if this information is not available or important to device management, the property should be set to 0 (zero).

For more information about using uint64 values in scripts, see Scripting in WMI.

This property is inherited from CIM_DeviceConnection.

NumberOfHardResets

Data type: uint32

Access type: Read-only

Number of hard resets issued by the controller. A hard reset returns the device to its initialization or boot-up state. All internal device state information and data are lost.

This property is inherited from CIM_ControlledBy.

NumberOfSoftResets

Data type: uint32

Access type: Read-only

Number of soft resets issued by the controller. A soft reset does not completely clear current device state and data. Exact semantics are dependent on the device and on the protocols and mechanisms used to communicate to it.

This property is inherited from CIM_ControlledBy.

Remarks

The Win32_IDEControllerDevice class is derived from CIM_ControlledBy.
