What disk is the drive on?

Recommended Posts



I'm trying to create an Auto-IT script that when given a drive letter the program will find out what disk number it is on. (e.g: Drive C: is on Disk 0). I've been trying to look at WMI to see if I can get it but i can't find a function that will help me with what I need.

Here's an example using WMI.

#include <Array.au3>

Func _GetLogicalDriveToPartition()
    $objWMIService = ObjGet("winmgmts:{impersonationLevel=Impersonate}!\\.\root\cimv2")
    If Not IsObj($objWMIService) Then Return -1 ;Failed to Connect to WMI on Local Machine
    Local $arr[1][2]
    $colDevice = $objWMIService.ExecQuery("SELECT * from Win32_LogicalDiskToPartition")
    For $objItem in $colDevice
        ReDim $arr[UBound($arr)+1][2]
    $arr[0][0]="Disk #, Partition #"
    $arr[0][1]="Drive Letter"
    Return $arr
