  I have an Amiga which I purchased last November.  I purchased the external
disk drive at the same time.  My drives make a noise when in use which has
been described by several hardware-type friends as the result of a slow
step-rate.  I am told that the step-rate is controlled by software, and
that the noise is the heads being jerked around, starting and stopping all
the time.  A correct step rate, they tell me, keeps the heads in constant
motion during use.  I am also told that there is nothing wrong with a slow
step rate, but that I might see a minor disk i/o speed improvement with the
correct rate.
  I obviously do not know what I am talking about, but what I understand
from all this is that I might be able to make the software run my disks a
little quieter, if someone who knows how would volunteer the information.
  An interesting point in all this is that newer drives do not make this
noise, running the same software.  This means either that the problem is not
software, or the step-rate correctly matches the newer drives.  I have
suspected for some time that the vendor or model of the drives changed after
my machine was shipped, but the store will not let me open one to see.
  Would someone (C= maybe?) comment on this?  Can I change the step rate?
Do I need to?  Are newer drives different?
