One way to avoid this problem is to avoid using the older quik-11 format
/dev/rst0 - I always use /dev/rst8 (quik-24 format).  Things seem to work
fine for me using the command exactly as described in the Sun manual:

	dump 0ucfs /dev/nrst8 600 /dev/rsd0g

the c option says this is a cartridge tape; the s option with parameter
600 says the tape length is 600 ft (if you leave it out dump will assume a
450 foot tape).  Since I use /dev/nrst8 the tape doesn't rewind when done.
When I take the tape out and look at it, it looks like most of the tape
has been used.  The number of tapes that dump says I need has so far been
pretty accurate.
