| Requesting logic check |

I'm working on learning WMI, and I'm trying to understand the whole event concept. Tell me if this seems reasonable to you:
Problem: I need to detect the event of a removable disk being inserted into a computer (i.e. a USB flash drive).
Fact: WMI provides a class called __InstanceCreationEvent, which informs WMI event consumers that an instance of something was just created.
Fact: WMI also provides a class called Win32_LogicalDisk, whose instances describe various disks that are currently available in the system.
Supposition: If all drives on a computer are represented by instances of Win32_LogicalDisk, then the insertion of a removable drive should trigger the creation of a new instance.
Proposed Solution: I can register an event query for the creation of any instance of Win32_LogicalDisk where the instance's DriveType property equals 2 (representing a removable disk).
Seems logical enough, yes? I've been told by others that WMI doesn't work this way, but I'll test this when I get home (I should have left work 20 minutes ago...) |
