WMI class ' Win32_DiskDrive ' reference for C# and VB.NET

MOF Reference

[Description("The Win32_DiskDrive class represents a physical disk drive as seen by a computer running the Win32 operating system. Any interface to a Win32 physical disk drive is a descendent (or member) of this class. The features of the disk drive seen through this object correspond to the logical and management characteristics of the drive. In some cases, this may not reflect the actual physical characteristics of the device. Any object based on another logical device would not be a member of this class.\nExample: IDE Fixed Disk."): ToSubClass, AMENDMENT, LOCALE(1033)]

	[Description("The Manufacturer property indicates the name of the disk drive manufacturer.\nExample: Seagate"): ToSubClass] string Manufacturer;
	[Description("The MediaLoaded property determines whether the media for a disk drive is loaded.  For fixed disk drives, this property will always be TRUE \nValues: TRUE or FALSE. If TRUE, the media is loaded."): ToSubClass] boolean MediaLoaded;
	[Description("The MediaType property is the type of media used or accessed by this device.\nExample: Removable media"): ToSubClass, Values{"Removable media", "Fixed hard disk", "Unknown"}: ToSubClass] string MediaType;

WMI is a huge subject, so therefore it is practically impossible to provide a comprehensive example program that covers anything. However, the book “Network programming in .NET” (Buy at Amazon UK) (Buy at Amazon US) covers a much wider scope of WMI, and explains how to leverage it to access the bounty of information held within this vast, yet simple object model.
