There has to be a static property...
*Edit:* Oh I know! We can let the menu autoupdate it...

You can also use WMI. Register a WMI Sink with ExecNotificationQueryAsync for a particular device class like Win32_LogicalDisk, then inspect any notifications sent. Off the top of my head I can't remember all the properties available for logical disks, but there may be something there of use. This method is also good because it is just as passive as using Windows notifications.

I'm not sure if you're familiar with AutoIt, but here's an example I have of what I'm talking about -

$wmiSink = ObjCreate("WbemScripting.SWbemSink")
ObjEvent($wmiSink , "SINK_")

$Obj_WMIService = ObjGet('winmgmts:\\localhost\root\cimv2')

If Not @error Then
	$obj_WMIService.ExecNotificationQueryAsync($wmiSink, "SELECT * FROM __InstanceOperationEvent WITHIN 1 WHERE TargetInstance ISA 'Win32_LogicalDisk'")
    ConsoleWrite("Ready and waiting for changes" & @CRLF)
EndIf

While 1
    Sleep(1000)
WEnd

Func SINK_OnObjectReady($objLatestEvent, $objAsyncContext)
	Switch $objLatestEvent.Path_.Class
		Case "__InstanceCreationEvent"
			ConsoleWrite("->==========================================" & @CRLF)
			ConsoleWrite("> Creation Event" & @CRLF)
			
		Case "__InstanceDeletionEvent"
			ConsoleWrite("->==========================================" & @CRLF)
			ConsoleWrite("> Deletion Event" & @CRLF)
			
	EndSwitch
	; Access:
	; 0 - Unknown
	; 1 - Readable
	; 2 - Writable
	; 3 - Read / Write Supported
	; 4 - Write Once
	Switch $objLatestEvent.Path_.Class
		Case "__InstanceCreationEvent", "__InstanceDeletionEvent"
			ConsoleWrite("Access: " & $objLatestEvent.TargetInstance.Access & @CRLF)
			ConsoleWrite("Caption: " & $objLatestEvent.TargetInstance.Caption & @CRLF)
			ConsoleWrite("Description: " & $objLatestEvent.TargetInstance.Description & @CRLF)
			ConsoleWrite("DeviceID: " & $objLatestEvent.TargetInstance.DeviceID & @CRLF)
			ConsoleWrite("DriveType: " & $objLatestEvent.TargetInstance.DriveType & @CRLF)
			ConsoleWrite("FileSystem: " & $objLatestEvent.TargetInstance.FileSystem & @CRLF)
			ConsoleWrite("FreeSpace: " & Int($objLatestEvent.TargetInstance.FreeSpace / 1000000) & " MB" & @CRLF)
			ConsoleWrite("Name: " & $objLatestEvent.TargetInstance.Name & @CRLF)
			ConsoleWrite("Size: " & Int($objLatestEvent.TargetInstance.Size / 1000000) & " MB" & @CRLF)
			ConsoleWrite("VolumeSerialNumber: " & $objLatestEvent.TargetInstance.VolumeSerialNumber & @CRLF)
			ConsoleWrite("->==========================================" & @CRLF)
	EndSwitch

I really don't understand the problem y'all are trying to fix (detecting drive insertion), but using the method Wraitdu suggested would be your best bet. Just compare the known drive letters from one instance to another for a change, say check every 1 second. Once a change is detected do [stuff]. Problem is, if the code is on the portable drive itself, the event is triggered *before* the code can run and thereby detect said event. It would need to be resident on the machine or on another removable drive and be running when the drive is inserted.

Within the "sink" mentioned by Wraitdu, put the know drive letters into an array and either check the array for changes or at what position the last drive letter appears. If a new letter appears or the last detected drive letter moved from var(4) to the var(5), you know something happened like a drive was added. then yoyu could scan the new drive and check it's drivetype.
