In comp.periphs.scsi you write:

You might try checking the power available at the disk, especially the
+5 voltage.  If it is marginal, you will see that behavior.

SunOS 4.1 has one, but in my experience it's no good (at least on our
Micro 1588-15).  I found that (ncyl=1627, acyl=2, pcyl=1632, nhead=15,
nsect=53) works well.
