We just got through doing this.  I did what was suggested, make all
the 18 track tapes read only.  The problem with the second message,
that the drive is not 36 track capable may be because a cart was
created while you were using the 3490e drives in 36track mode and now
that you have gone back to the 3480's it cannot be read.
