I am guessing that the lack of a 'C' at the end of this event name means that it is not the same as most other Control events. It actually is more of a Notification style event, correct? Therefore, I can't actually block the system from mounting the FS with this event?

You may block on this event. It behave like notification event.

Notifications events occur after the event has already happened right? So therefore it would be too late to block.

In your CBFilter sample (Using VS2008), I added:
mCbFlt.OnFilterAttachToFsVolume = new CbFltFilterAttachToFsVolumeEvent(CbFltFilterAttachToFsVolume);
to the constructor and a callback event handler:
void CbFltFilterAttachToFsVolume(
object Sender,
string VolumeName )
MessageBox.Show("FS ATTACH Volume - " + VolumeName);

The message box pops up, but even before closing the msg box, the fs volume gets mounted and is available for the user to browse to and use in windows explorer. Am I missing something else that I need to do to block the volume from being mounted?

Saying that you can block on this event i mean that you may delay the execution of this event for any reasonable time without chances to block the file system work. You cannot block the mounting process from this event.
