I'm already doing this. Problem that's arisen is USB external drives 
are DriveType 3 (Local Fixed Disk) while USB memstiks are DriveType 2 
(Removable Disk). So filtering on these in "LogicalDisk" doesn't relate 
to the hardware found in "DiskDrive". The only thing I've seen from 
"DiskDrive" that appears anywhere in Windows UI is "DiskDrive.Name 
[Model]". This is the same info that shows up in the properties 
dialog>Hardware tab AllDrives list. So I was hoping there's an API that 
will return a drive letter for a specified drive name.

Yes, I did say I was going to do that. However, I already know what 
you've shared here and so I'm not looking for WMI help.
