Returns the decimal serial number used to uniquely identify a disk volume.

The object is always a Drive object.

You can use the SerialNumber property to ensure that the correct disk is inserted in a drive with removable media.

The following code illustrates the use of the SerialNumber property:

Sub ShowDriveInfo(drvpath)
    Dim fs, d, s, t
    Set fs = CreateObject("Scripting.FileSystemObject")
    Set d = fs.GetDrive(fs.GetDriveName(fs.GetAbsolutePathName(drvpath)))
    Select Case d.DriveType
        Case 0: t = "Unknown"
        Case 1: t = "Removable"
        Case 2: t = "Fixed"
        Case 3: t = "Network"
        Case 4: t = "CD-ROM"
        Case 5: t = "RAM Disk"
    End Select
    s = "Drive " & d.DriveLetter & ": - " & t
    s = s & vbCrLf & "SN: " & d.SerialNumber
    MsgBox s
End Sub
