Win32_IDEControllerDevice

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

Quick Start

Properties

In this WMI class, all WMI properties are read-only. You can only read values but not change them.

AccessState

Data type UInt16

The AccessState property indicates whether the controller is actively commanding or accessing the device (value=1) or not (value=2). Also, the value, “Unknown” (0), can be defined. This information is necessary when a logical device can be commanded by, or accessed through, multiple controllers.

Antecedent

Data type Reference

The Antecedent reference represents the IDE controller associated with this device.

Dependent

Data type Reference

The Dependent reference represents the CIM_LogicalDevice connected to the IDE controller.

NegotiatedDataWidth

Data type UInt32

When several bus and/or connection data widths are possible, the NegotiatedDataWidth 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/important to device management, the property should be set to 0.

NegotiatedSpeed

Data type UInt64

When several bus and/or connection speeds are possible, the NegotiatedSpeed property defines the one in use 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/important to device management, the property should be set to 0.

NumberOfHardResets

Data type UInt32

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.

NumberOfSoftResets

Data type UInt32

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