The Win32_PhysicalMedia class has these properties.
Number of bytes that can be read from or written to this physical media component. This property does not apply to "Hard Copy" or cleaner media. Data compression should not be assumed as it would increase the value of this property. For tapes, it should be assumed that no filemarks or blank space areas are recorded on the media.
Short, one-line textual description of the object.
If TRUE, the physical media is used for cleaning purposes and not data storage.
Name of the class or subclass used in the creation of an instance. When used with other key properties of this class, CreationClassName allows all instances of this class and its subclasses to be uniquely identified.
Textual description of the object.
If TRUE, this physical media component can be replaced with a physically different but equivalent one while the containing package has the power applied. For example, a fan component may be designed to be hot-swapped. All components that can be hot-swapped are inherently removable and replaceable.
When the object was installed. This property does not require a value to indicate that the object is installed.
Name of the organization responsible for producing the physical element. This can be the entity from whom the element is purchased, but this is not necessarily the case as this information is contained in the Vendor property.
Additional detail related to the MediaType property. For example, if MediaType has the value 3 (QIC Cartridge) the MediaDescription property can indicate whether the tape is wide or quarter inch.
The type of the media, as an enumerated integer. The MediaDescription property provides a more explicit definition of the media type.
The following list lists the possible values.
CD ROM
CD ROM/XA
Name by which the physical element is generally known.
Additional data, beyond asset tag information, that can be used to identify a physical element. One example is bar code data associated with an element that also has an asset tag. Note that if only bar code data is available, is unique, and it can be used as an element key, this property is NULL and the bar code data used is the class key in the Tag property.
Part number assigned by the manufacturer of the physical element.
If TRUE the physical element is powered on.
If TRUE, the physical component is designed to be taken in and out of the physical container in which it is normally found, without impairing the function of the overall packaging. A component can still be removable if the power must be "off" to perform the removal. If power can be "on" and the component removed, the element is removable and can be hot-swapped.
If TRUE, this physical media component can be replaced with a physically different one. For example, some computer systems allow the main processor chip to be upgraded to one of a higher clock rating. In this case, the processor is said to be replaceable. All removable components are inherently replaceable.
Manufacturer-allocated number used to identify the physical media. The default value is NULL.
Example: WD-WM3493798728
Stock keeping unit number for this physical element.
Current status of the object. Various operational and nonoperational statuses can be defined. Operational statuses are "OK", "Degraded", and "Pred Fail". "Pred Fail" indicates that an element may function properly at the present, but predicts a failure in the near future. For example, a SMART-enabled hard disk drive. Nonoperational statuses can also be specified. These are, "Error", "Starting", "Stopping," and "Service". The "Service" status applies to administrative work, such as mirror-resilvering of a disk or reload of a user permissions list. Not all such work is online, yet the managed element is neither "OK" nor in one of the other states.
The values are:
OK ("OK")
Error ("Error")
Degraded ("Degraded")
Unknown ("Unknown")
Pred Fail ("Pred Fail")
Starting ("Starting")
Stopping ("Stopping")
Service ("Service")
Stressed ("Stressed")
NonRecover ("NonRecover")
No Contact ("No Contact")
Lost Comm ("Lost Comm")
Uniquely identifies the physical media in the system.
Example: PHYSICALDRIVE0
Version of the physical element.
If TRUE, the media is currently write protected by some kind of physical mechanism, such as a protect tab on a floppy disk.
