   var fso = new ActiveXObject("Scripting.FileSystemObject");
   var e = new Enumerator(fso.Drives);

   e.moveFirst();
   while (e.atEnd() == false)
   {
      var x = e.item();

      s += x.DriveLetter;
      s += " - ";

      if (x.DriveType == 3)
         s += x.ShareName;
      else if (x.IsReady)
         s += x.VolumeName;
      else
         s += "[Drive not ready]";

      s += "\n";
