Thanks, Reid.
Both clients who have had this problem are using the MAXTAPEBUF option.
But, this doesn't happen most of the time, only periodically.  Now that I
look at it,
it appears all of the time, as:

NON DEFAULT MEDIA BUFFER SIZE BEING USED.
CURRENT MEDIA RECORD SIZE IS: 32768.

So, nevermind the initial question.  My next question is, why would the
drive not STORE
one day but do so fine other days.  The "going bad" explanation doesn't
explain, necessarily,
why a new drive would do this.  Could it be the media going bad?  (It could
be a new drive that
is not up to QA, but not likely.)  Thanks for your help.
James
