We have a DECstation 3100 with an RZ56 disk and are also experiencing a
high noise level from the disk.  However, we have not informed DEC of
the problem as yet.  We have the feeling the the spindle is rubbing
against something, possibly the disk enclosure???  Maybe we should get
the local DEC engineers involved.
