I have a few comments. First, I'd recommend moving the header data into
sectors of it's own, this maintains the size of each sector, something that
will help you a great deal in maintaining usability (just report the disk as
smaller and take the outer most sectors). Second, if you journal the disk so
that you dynamically reassign sectors, you can fairly easily write the
sector, write the header data, write the sector remapping, this fails safe
because if the remap data isn't written it will point to the old sector with
the old sector header. This has problems with fragmentation, but if you run
a background task that perform the disk ordering it shouldn't be too bad.
