Spot,

We have a Sun 3/260 running SunOS 4.0.  The tapes that I buy for the Sun
say on them "600'", which I assume means 600 feet.  However, when I use
dump, and specify a size longer than 600', it does not fail until
somewhere near 1000' (at least that is what it reports).  I have been
specifying 900' for some time now with no problems.  Does anyone know what
is going on?  Is the tape actually 1000', or is dump broken?

I was using the tape via the /dev/rst0 driver.  Is there any good reason
to use /dev/rst8 instead?
