I don't like to use the extra-tracks/extra-sectors capabilities of
fdformat because I sometimes use disks in drives that can't handle the
excess.  Nonetheless I still like fdformat for its ability to offset
sectors between tracks; I clocked small but consistent improvements in
my 3.5" access times by using some sector- and track-sliding, and the
3.5" drive strikes me as slow enough to need all the help it can get.

I also like the way fdformat creates boot sectors that know to go to the
hard disk at reboot time if there's no O.S. on the floppy in the A: drive.
That's real convenient.
