Hi
 For 8 inchers, I doubt that their are any that
are fast enough for the standard 5-1/4 step rates.
 There was a program out there that modifies the
step rates. I know it is on the web someplace.
As I recall, it would try the full span of steps
available and watch for errors. I would guess that
this would work for your 8 inchers, even though,
it was inteneded to be used to optimize the steps
for faster drives.
 Maybe one of the others can remember what it is called.
Of course, you are always the one that states that one
should do a good google search first ;)
