Members

The SystemConfig_V0_PhyDisk class has these types of members:

• Properties

Properties

The SystemConfig_V0_PhyDisk class has these properties.

BootDriveLetter

Data type: char16 array

Access type: Read-only

Qualifiers: WmiDataId (13), Max (3)

Drive letter of the boot drive in the form, "<letter>:".

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: char16 array

Access type: Read-only

Qualifiers: WmiDataId (10), Max (256)

Name of the disk drive manufacturer.

PartitionCount

Data type: uint32

Access type: Read-only

Qualifiers: WmiDataId (11)

Number of partitions on this physical disk drive that are recognized by the operating system.

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.

WriteCacheEnabled

Data type: boolean

Access type: Read-only

Qualifiers: WmiDataId (12)

True if the write cache is enabled.
