I've received five responses so far and do not except more; hence the
summary. I've ordered them in, what I consider, order of significance.
But do examine all.
Of the five, the first one below, from Michael Sullivan, has helped
solve my problem. Thanks, Michael for a most comprehensive answer.
BTW, I have asked Michael for the numbers of the OEM manuals as I
believe this info will permit me to get a set.
While awaiting responses I entered a call into Sun Canada's customer
service department and received much the same information that Michael
provided except without the detail. According to Sun there are no
SunOS patches that affect the drive; but Mory Katz' message forces me
to scrutenize the available patches much more closely. Hopefully a
patch will be found.
Thanks to all for the quick help,

In article <firstname.lastname@example.org> you write:

We have a similar set up here with a 4/380 and what sounds like the same tape
drive (I presume you meant "1/2-inch") except ours came directly from HP. We
are running SunOS4.1.1, but I don't think that is the problem (although I
should warn you that if you are planning on upgrading to 4.1.1, be sure to get
patch 100250-01, which fixes an annoying bug with the MTFSR and MTBSR ioctls
that caused tar appends to silently fail).
