12=Install Error
13=Power Save - Unknown
14=Power Save - Degraded
15=Power Save - Standby
16=Power Cycle

BytesPerSectoruint32512Indicates the number of bytes per sector of the physical disk drive.
Capabilitiesstring"3"Indicates the capabilities of the MediaAccessDevice.

Values are:
0=Unknown
1=Other
2=Sequential Access
3=Random Access
4=Supports Writing
5=Encryption
6=Compression
7=Supports Removable Media

Captionstring Describes the object. Maximum length is 64 characters.
Descriptionstring"IDE Fixed Disk"Describes the object.
DeviceIDstring"\\\\.\\PHYSICAL
DRIVE0"		Key. Provides an address or other identifying information to uniquely name the LogicalDevice. Maximum length is 64 characters.
ErrorMethodologystring Describes the types of error detection and correction that the device supports.
GroupIDuint322Within one ResourceId (one SMS client), GroupID distinguishes one instance of a class from another. Objects with the same ResourceId and GroupID are “deltas” of one another, describing the same hardware inventory instance at different points in time. This is not a collectable property.
Indexuint321Indicates the index number of the disk drive.
InstallDatedatetimeSee “Date and Time Formats” at the beginning of Appendix B.Indicates when the object was installed. The absence of a value does not indicate that the object is not installed.
InterfaceTypestring"IDE"Indicates the interface type of the physical disk drive.
Manufacturerstring"Seagate"Indicates the name of the disk drive manufacturer.
MediaLoadeduint321Determines whether the media for a removable disk drive are loaded.

Values are:
1=True
0=False

If the value is True, the media are loaded.

MediaTypestring"Fixed hard disk"Indicates the type of media used or accessed by the device.
Modelstring"ST32171W"Indicates the manufacturer’s model number of the disk drive.
Namestring"\\\\.\\PHYSICAL
DRIVE0"		Defines the label that the object is known by. Maximum length is 256 characters.
NumberOfMediaSupporteduint321Defines the maximum number of media that can be supported or inserted when the MediaAccessDevice supports multiple individual media.
Partitionsuint322Indicates the number of partitions on the physical disk drive.
PNPDeviceIDstring  
PowerManagementSupporteduint321A Boolean that indicates that the ComputerSystem and its running OperatingSystem support power management. This Boolean does not indicate that power management features are currently enabled or if they are enabled, which features are supported.

Values are:
1=True
0=False

ResourceIduint3242Key. Inventory items with the same ResourceId were all discovered on the same SMS client. The ResourceId identifies the SMS client.

A ResourceId is an integer generated for the sake of SQL; it is not unique outside the site and should be used only for short-term querying purposes. It is not a collectable property.

RevisionIDuint321Objects with the same ResourceId and GroupID are deltas, differentiated from one another by RevisionID number. The highest number is the most recent update. This is not a collectable property.
SCSIBusuint320Indicates the SCSI bus number of the disk drive.
SCSILogicalUnituint320Indicates the SCSI logical unit number (LUN) of the disk drive.
SCSIPortuint320Indicates the SCSI port number of the disk drive.
SCSITargetIduint320Indicates the SCSI ID number of the disk drive.
SectorsPerTrackuint3263Indicates the number of sectors per track of the physical disk drive.
Sizeuint322510Megabytes. Indicates the size of the disk drive.
Statusstring"OK"Indicates the current status of the object.

Values are:
OK
Error
Degraded
Unknown

Maximum length is 10 characters.

StatusInfostring"3"A string that indicates the state of the LogicalDevice.

Values are:
1=Other
2=Unknown
3=Enabled
4=Disabled
5=Not Applicable

SystemNamestring"SMS20NTWKS"Provides the scoping system’s name. Maximum length is 256 characters.
TimeStampdatetimeSee “Date and Time Formats” at the beginning of Appendix B.Indicates when the information in this object was last revised. This is not a collectable property.
TotalCylindersuint320Indicates the total number of cylinders on the physical disk drive.
TotalHeadsuint3264Indicates the total number of heads on the disk drive.
TotalSectorsuint322649024Indicates the total number of sectors on the physical disk drive.
TotalTracksuint3242048Indicates the total number of tracks on the physical disk drive.
TracksPerCylinderuint3264Indicates the number of tracks per cylinder on the physical disk drive.
