I am developing a script that needs to run on a PC that does not have a CD/DVD drive (mine both do), so I need to know the answer -- an easy one to answer for someone without a CD/DVD drive. If there is no CD/DVD drive, perhaps DriveGetDrive('CDROM") returns [0] or sets @error, or both.

$Drive = DriveGetDrive("CDROM") ; = ""
If @error Then
   MsgBox (0,"",@error) ; No @error
EndIf

MsgBox (0,"",$Drive)

Don't have CD-Rom

I mean, how hard is it to check the help file?

Better is to make a little testscript (c&p from help, with 1 additional MsgBox):

#include <AutoItConstants.au3>
#include <MsgBoxConstants.au3>

Local $aCDRom = DriveGetDrive($DT_CDROM )
If @error Then
    ; An error occurred when retrieving the drives.
    MsgBox($MB_SYSTEMMODAL, "", "It appears an error occurred.")    ;this MsgBox appears
Else
    MsgBox(64, 'CDRom Drive',$aCDRom[0] & ' CD-Drives found')   ; i expected this MsgBox : 0 CD-Drives found
    For $i = 1 To $aCDRom[0]
        ; Show all the drives found and convert the drive letter to uppercase.
        MsgBox($MB_SYSTEMMODAL, "", "Drive " & $i & "/" & $aCDRom[0] & ":" & @CRLF & StringUpper($aCDRom[$i]))
    Next
EndIf

The help file says that on failure DriveGetDrive() set @error to 1

But is not having a CD drive considered as "failure"?

Perhaps someone who does not have a CD drive run AutoBert's script and tell me the results.

Thanks in advance.

----

DriveGetDrive('RAMDISK') on my system, that does not have a RAMDISK, sets @error to 1.

If DriveGetDrive('CDROM') is consistent with DriveGetDrive('RAMDISK'), not having a CD drive would cause @error to be set to 1.

Many thanks. So I will assume that DriveGetDrive() consistently sets @error for "no such thing".
