    var bytesPerGB = 1024 * 1024 * 1024;

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

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

        s += drv.Path + " - ";

        if (drv.IsReady)
        {
            var freeGB = drv.FreeSpace / bytesPerGB;
            var totalGB = drv.TotalSize / bytesPerGB;

            s += freeGB.toFixed(3) + " GB free of ";
            s += totalGB.toFixed(3) + " GB";
        }
        else
        {
            s += "Not Ready";
