This is useful for image files which +might need additional zero-filled sectors to be inserted. Such is the +case for instance for IBM 3174 floppy images. These images represent +floppy disks with fewer sectors on their first cylinder. These missing +sectors are not stored in the image, but are still counted in the +filesystem layout.
