cimv2 object help

[senthor]

Hello everyone!

I'm currently trying to create a script were I need to recognize if a drive is connected.

It shouldn't take too long cause it will be looped. AND it should be without floppy access. (Maybe Win32_LogicalDisk without class floppy drives??)

till now I have:

$strComputer = "."
$objWMIService = ObjGet("winmgmts:\\" & $strComputer & "\root\cimv2")
$objEvent = $objWMIService.ExecNotificationQuery _
   ("Select * From __InstanceOperationEvent Within 5 Where " _
   & "TargetInstance isa 'Win32_LogicalDisk' and " _ 
   & "TargetInstance.DriveType = 2" )

While True
   If $objEvent.TargetInstance.DriveType = 2 Then
      If $objEvent.Path_.Class()="__InstanceCreationEvent"
         ~some code~
      Else
         ~some other code~
      EndIf
   EndIf
   Sleep(10)
WEnd

Otherwise, it would be OK if it would only list all drives without any floppy drives and access.

It shouldn't take too long cause it will be looped.

Thank you!

So... what happens when you run it?

My floppy drive gets accessed and it takes about 5-8 seconds to check drives. ;-(

Well, DriveType = 2 is removable drives, which includes floppies.

Limit the collection more by also specifying .MediaType, perhaps .MediaType = 11 or 12.

$strComputer = "."
$objWMIService = ObjGet("winmgmts:\\" & $strComputer & "\root\cimv2")
$objEvent = $objWMIService.ExecNotificationQuery _
   ("Select * From __InstanceOperationEvent Within 5 Where " _
   & "TargetInstance isa 'Win32_LogicalDisk' and " _ 
   & "TargetInstance.DriveType = 2" )

While True
   $objEvent = $objEvent.NextEvent
   If $objEvent.TargetInstance.MediaType = 10 or $objEvent.TargetInstance.MediaType = 11 Then
      If $objEvent.Path_.Class()="__InstanceCreationEvent"
         ~some code~
      Else
         ~some other code~
      EndIf
   EndIf
   Sleep(10)
WEnd

works, but takes a while too...

I meant add it as another "and" condition in your query.

[senthor]
