Then you're missing the point.  "length 0" just gives you the rest of
the volume.  Here you need to find the data which is already on disk.

There was an error in the first cut of this document.  Under some
circumstances it could lead to overwriting the bootstrap, thus making
the disk unbootable.  For further reference: the space required at the
beginning of the disk is 281 sectors, not 265 as originally
documented.  See the document for more details.
