Detect when drive letter is mounted

[Hamcher]

Hey all, this is my first time posting and I have had a little look around to see if I could find my issue before posting.

I am writing a script to detect when a drive (specific drive letter) is mounted, then run a file on that drive.

Currently I am using the USB mounting detection but that doesn't detect when a CF card is inserted into my reader, it only detects when I unplug the reader (with the card in it) then plug it back in. Below is my current code:

$DBT_DEVICEARRIVAL = "0x00008000"
$WM_DEVICECHANGE = 0x0219
GUICreate("")
GUIRegisterMsg($WM_DEVICECHANGE , "MyFunc")
Func MyFunc($hWndGUI, $MsgID, $WParam, $LParam)
If $WParam == $DBT_DEVICEARRIVAL Then
Run ("E:\run_emu.bat")
EndIf
EndFunc
While 1
$GuiMsg = GUIGetMsg()
WEnd

Any help would be greatly appreciated,

Cheers, Hamcher.

I think DriveGetDrive is a better option, and you can specify the type of drives:

#include <Array.au3>
Local $aDrives

$aDrives = DriveGetDrive('all')
_ArrayDisplay($aDrives)

I would then use FileExists to see if your file exists before just blindly continuing, and probably see if you can use something like FileGetVersion to make sure that you're running the right file/version of whatever you want:

#include <Array.au3>
Local $aDrives

$aDrives = DriveGetDrive('all')
_ArrayDisplay($aDrives)

For $iDrive = 1 To $aDrives[0]
    If FileExists($aDrives[$iDrive] & ':\run_emu.bat') = 1 Then
;~      If FileGetVersion($aDrives[$iDrive] & ':\run_emu.bat', 'FileVersion') = '1.0.0.0'
        ConsoleWrite('File is on drive: ' & $aDrives[$iDrive] & @CRLF)
        ExitLoop
    EndIf
Next

if I assume that "E:\run_emu.bat"  is on USB , else give a know path from USB in FileExists("E:\run_emu.bat")

Local $iFileExists = FileExists("E:\run_emu.bat")

    If $iFileExists Then
        Run ("E:\run_emu.bat")
    EndIf
