As far as I know, sectors are allocated by cylinder.  Thus sector 0 is
on the top and sector 1 is on the bottom of the first cylinder, etc.
This is done to enhance speed, since one can eliminate alot of
head seeks (which take a great deal of time) by allocating file sectors
intelligently.  Theoretically, with two sides one could eliminate
up to half of head seeks or steps.  It would be a nice option to be
able to format disks your way, but this might confuse some users.
I think all software houses should have an option in their copy
protected software to move it to an HFS volume (either 800K or
a hard disk).
