MOF Reference

[Description("The Win32_LogicalDisk class represents a data source that resolves to an actual local storage device on a Win32 system.\nThe class returns both local as well as mapped logical disks. However, the recommended approach is to use this class for obtaining information on local disks and to use the Win32_MappedLogicalDisk class for information on mapped logical disk."): ToSubClass, AMENDMENT, LOCALE(1033)]

A filename component is that portion of a filename between backslashes.  The value can be used to indicate that long names are supported by the specified file system.

Note that the calls to exclude disks are not cumulative. That is, if a call is made to excluded some disks, then the new list is not added to the list of ones that were already marked for exclusion, instead the new list of disks overwrites the previous one. The method is applicable to only those instances of logical disk that represent a physical disk in the machine and is not applicable to mapped logical drives. \nFor example, a valid specification of drives would be \"C:\", \"d:\",\"G:\"  Note that the colon is required with the drive letter."): ToSubClass, Values{"Success", "Error - Remote Drive", "Error - Removable Drive", "Error - Drive Not Root Directory", "Error - Unknown Drive"}: ToSubClass] uint32 ExcludeFromAutochk([in, Description("This parameter is used to specify the list of drives that should be excluded from autochk at next reboot.

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.
