HWConfig_PhyDisk class

  • Article

The HWConfig_PhyDisk class is the event type class for physical disk configuration events.

The following syntax is simplified from MOF code.

Syntax

[EventType(11), EventTypeName("PhyDisk")]
class HWConfig_PhyDisk : HWConfig
{
  uint32 DiskNumber;
  uint32 BytesPerSector;
  uint32 SectorsPerTrack;
  uint32 TracksPerCylinder;
  uint64 Cylinders;
  uint32 SCSIPort;
  uint32 SCSIPath;
  uint32 SCSITarget;
  uint32 SCSILun;
  string Manufacturer;
};

Members

The HWConfig_PhyDisk class has these types of members:

Properties

The HWConfig_PhyDisk class has these properties.

BytesPerSector

Data type: uint32

Access type: Read-only

Qualifiers: WmiDataId(2)

Number of bytes in each sector for the physical disk drive.

Cylinders

Data type: uint64

Access type: Read-only

Qualifiers: WmiDataId(5)

Total number of cylinders on the physical disk drive. Note: the value for this property is obtained through extended functions of BIOS interrupt 13h. The value may be inaccurate if the drive uses a translation scheme to support high capacity disk sizes. Consult the manufacturer for accurate drive specifications.

DiskNumber

Data type: uint32

Access type: Read-only

Qualifiers: WmiDataId(1)

Index number of the disk containing this partition.

Manufacturer

Data type: string

Access type: Read-only

Qualifiers: WmiDataId(10), StringTermination("NullTerminated"), Format("w")

Name of the disk drive manufacturer.

SCSILun

Data type: uint32

Access type: Read-only

Qualifiers: WmiDataId(9)

SCSI logical unit number (LUN) of the SCSI adapter.

SCSIPath

Data type: uint32

Access type: Read-only

Qualifiers: WmiDataId(7)

SCSI bus number of the SCSI adapter.

SCSIPort

Data type: uint32

Access type: Read-only

Qualifiers: WmiDataId(6)

SCSI number of the SCSI adapter.

SCSITarget

Data type: uint32

Access type: Read-only

Qualifiers: WmiDataId(8)

Contains the number of the target device.

SectorsPerTrack

Data type: uint32

Access type: Read-only

Qualifiers: WmiDataId(3)

Number of sectors in each track for this physical disk drive.

TracksPerCylinder

Data type: uint32

Access type: Read-only

Qualifiers: WmiDataId(4)

Number of tracks in each cylinder on the physical disk drive. Note: the value for this property is obtained through extended functions of BIOS interrupt 13h. The value may be inaccurate if the drive uses a translation scheme to support high capacity disk sizes. Consult the manufacturer for accurate drive specifications.
