<OK, I know what a track and a sector is, but what is the difference
<between hardsector and softsector
Hardsectored uses physical landmarks like index and sector holes on the
media to locate sectors.
Softsector uses various data marks on the media to locate the data.
It's possible to do a hard sector scheme that looks like softsector but,
the difference between them in older machines is the basic format is such
that most controller chips like the 372, 1771, 1791, 8271 and 765 cannot
read them.
Apple combined and simplified the disk controller to software and some
trivial logic.
