The physical disks on Windows devices.

Column	Description

Column	Description
DeviceGuid	The device that the disk drive belongs to.
FirmwareRevision	A manufacturer-allocated number used to identify the physical media.
Index	The physical drive number of the given drive. This member is filled by Get Drive Map Info. A value of 0xFF indicates that the given drive does not map to a physical drive. For example: 1.
InstallDate	The date and time the object was installed. This property does not need a value to indicate that the object is installed.
InterfaceType	Indicates the interface type of physical disk drive. For example: SCSI.
LastErrorCode	Captures the last error code reported by the logical device.
Manufacturer	Indicates the name of the disk drive manufacturer. For example: Seagate.
MediaType	The type of media used or accessed by this device. For example: Removable media.
Model	The manufacturer's model number of the disk drive. For example: ST32171W.
Name	The label by which the object is known. When subclassed, the property can be overridden to be a key property.
SerialNumber	A manufacturer-allocated number used to identify the physical media. For example: WD-WM3493798728 for a disk serial number.
Size	Indicates the size of the disk drive. Calculated by multiplying the total number of cylinders, tracks in each cylinder, sectors in each track, and bytes in each sector.
Status	The current operational or non-operational status of the object. Operational statuses include: "OK", "Degraded", and "Pred Fail" (an element, such as a SMART-enabled hard disk drive, may be functioning properly but predicting a failure in the near future). Non-operational statuses include: "Error", "Starting", "Stopping", and "Service". The status "Service" could apply during mirror-resilvering of a disk, reload of a user permissions list, or other administrative work. Not all such work is online, yet the managed element is neither "OK" nor in one of the other states.
