How to find the driveletter of an USB device

5 posts in this topic

Maybe a stupid question, but is there a way to find the driveletter of an USB device wich is plugged in?

I have some people who want to make a backup to an USB device. I could put the driveletter wich it have it now in the script, but as you know this will not guarantee for the future.

I know there are some programs wich can detect the USB device and i really would like to know how i can accomplish this with AutoIT also.

Anyone any idea?

Someone posted a DISKPART UDF in the example scripts forum. However, as of now, it cannot return the type of drive you're using. I did something very similar to this a few months back but I went about it in a round about way. I basically did a DISKPART dump to a txt file and then had AutoIt read lines from that text file. It would return the disk type that it read from the outputted DISKPART log. This is probably NOT the way to do it. I don't know if there are WMI calls that would be a lot easier.

Here is a start

$var = DriveGetDrive("REMOVABLE")
If Not @error Then
    MsgBox(4096, "", "Found " & $var[0] & " drives")
    MsgBox(4096, "Drive ", $var[$var[0]])
EndIf

This is a start, yes. But i am a big sucker at arrays :">

Most new PC's got internal card readers wich are detected also as REMOVABLE, so is it possible to detect te drives and check for the name wich i can predefine?

Ex. USB stick name is USBDISKPRO and the drive letter is P:\, is it possible to find out just this specific driveletter?

You could use DriveGetLabel on the removeable drives to see which one matches.

Edit - added code

$var = DriveGetDrive("REMOVABLE")
If Not @error Then
    MsgBox(4096, "", "Found " & $var[0] & " drives")
    For $i = 1 To $var[0]
        If DriveGetLabel($var[$i]) = "test" Then
            MsgBox(4096, "", "Removable disk is " & $var[$i])
        EndIf
    Next
EndIf
