Detecting USB Removal

[bartonjd]

I would like to write a script that will perform an action when I pull my USB drive out of the slot, e.g. lock my windows session. I found >this script which can detect a usb insertion. However I want to detect if a USB drive with a specific name is ejected. Is there any way to do this?

You could convert this C# WMI call:

Assuming the USB is already inserted when the script runs, I'd use this:

#include <MsgBoxConstants.au3>

Local $aArray = DriveGetDrive("ALL")
Local $ourDrive = ""

If @error Then
    MsgBox($MB_SYSTEMMODAL, "", "It appears an error occurred while enumerating the drives, exiting...")
Else
    For $i = $aArray[0] To 1 Step -1
        If DriveGetLabel($aArray[$i]) = "win7_usb" Then
            $ourDrive = $aArray[$i]
            ExitLoop
        EndIf
    Next
EndIf

If Not $ourDrive Then
    MsgBox($MB_SYSTEMMODAL, "", "Our drive was not found, exiting...")
    Exit
EndIf

While True
    Sleep(2000)
    if DriveStatus($ourDrive) <> "READY" Then
        MsgBox($MB_SYSTEMMODAL, "", "Our drive was REMOVED !!!")
        Exit
    EndIf
WEnd

If you want to know when the user ejects a usb device then look at RegisterDeviceNotifications in my signature.
