When I image disked my set, it found both 8 and 10
sector disks. The 3B1 can
format in either 8 or 10 sectors. It looks like the main
software is all in 10
sector
disks and the other add on software is
in 8 sectors. The 2 disks that failed to
image
where from the same add on package, don't remember which and they showed
up as 9 sectors ??? Anadisk finds the same and can read the first 8 sectors and
errors on the 9th.
As I recall, earlier distributions of the system were all
on 8 sectored disks. But as the distributions grew, they
started using 10 sectors to fit more on the disk. But I
do remember that at least one of the disks was always 8
sectors. I'm inclined to say that might have had to do
with the on-board boot code. The PROM code may not have
been able to boot from a 10 sectored disk, but that's as
much or more speculation as it is memory.
