That's correct.  After I wrote the PC/DOS partition, cfdisk has not
complained again.

I'll try disabling both of these & see how things go.  Are either of these
likely to cause intermittent access problems?  Given that running badblocks
doesn't produce any kernel error messages, it occurs to me that this
could be a disconnect/reconnect issue.  'Synchronous SCSI' is disabled when
the driver is loaded; I don't think it should be re-enabling itself later.

That can't be the problem here; this is the only SCSI drive/controller
I have.
