DriveGetDrive not working ?Get available drive letters

[nadigo]

Hi,

I am trying to get an available drive letter (a one that is not used by local HD, CDROM, network share or any other) during script run time in order to use that Drive letter to mount a file system

.

I use the

DriveGetDrive("ALL")

to list the existing disks and eliminate if from Z-A order.

I get the letter "Z" even when there is a mounted network share on the dirve ("Z") why ??

Thnaks,

Nadav

Func GetFreeDriveLatter ()
 
$DriveArray = DriveGetDrive("ALL")

;_ArrayDisplay ($DriveArray)

Global  $AtoZ [27] = ["25","A","B","C","D","E","F","G","H","I","J","K","L","M","N","O","P","Q","R","S","T","U","V","W","X","Y","Z"]
            
                For $i = 26  to 1 Step -1 
                    For $DriveCount = 1 to $DriveArray[0]
                        If  StringInStr (($DriveArray[$DriveCount]), $AtoZ[$i], 0) Then $AtoZ[$i] = False
                    Next
                Next

;_ArrayDisplay ($AtoZ) 

    For $i1 = 26 to 1 Step -1 
        If $AtoZ[$i1] <> False  Then 
            $MountDrive = StringUpper($AtoZ[$i1])
            ExitLoop
        EndIf   
    Next
    
    
    Return ($MountDrive)    

EndFunc

i think you have some array problem, its mess in there

try like this and tellme do the Z have false on msgbox?

#Include <Array.au3>
MsgBox(0,"",GetFreeDriveLatter())
Func GetFreeDriveLatter ()
    $DriveArray = DriveGetDrive("ALL")
    $listtemall = "A,B,C,D,E,F,G,H,I,J,K,L,M,N,O,P,Q,R,S,T,U,V,W,X,Y,Z"
    For $x = 1 To $DriveArray[0]
        If StringInStr($listtemall,StringReplace($DriveArray[$x],":","")) Then $listtemall = StringReplace($listtemall,StringReplace($DriveArray[$x],":",""),"False")
    Next
    Return $listtemall
EndFunc

DriveGetDrive doesn't recognize mounted network.

So, if possible (i don't know about mounted network), try to add a condition if drive already exists...

"ALL", "CDROM", "REMOVABLE", "FIXED", "NETWORK", "RAMDISK", or "UNKNOWN"

so it shud detect network drive connected (maped) to PC
