In my summary, I mentioned a couple of errors that appeared after formatting
the CDC 9720-1230 drives:

Thanks to the following two gentlemen:
Jeff Nieusma <nieusma@cs.Colorado.EDU>
John Valdes <valdes@geosun.uchicago.edu>
This problem is now resolved. There is a jumper on these drives which can
enable or disable a 'sweep cycle'. This function was enabled, however, Sun
doesn't support it. Disabling it eliminated the problem. Thanks again.
