I agree, "never" is a big word. I suddenly came to think of that I have
read quite some hard-sectored disks in my 8" drive, so yes, "never" is
wrong. On the other hand, I've seen an occasion where a (5.25") drive
reacted on every hole as if it was an index hole, so believning that the
drives spins at 12x (or whatever) normal speed.
