The code doesn't try to set the density unless you do explicitly.

However, you need the patch i've posted, or you need ``mt fsr 1; mt
rewind'' first.  The Tandbergs don't MODE SENSE useful data unless
they have already at least one tape block (but the FreeBSD tape driver
relies on useful data from MODE SENSE, since it passes them on to a
MODE SELECT).
