Have you tried matching up that 'transfer limit' with dump's '-b'
option?

# dump -0b 26 -f /dev/rwst0 /var

Have you tried using the 'auto-size' option, '-a'?

# dump -0af /dev/rwst0 /var

Or even doing both of those together?

Just some ideas. I personally do not have experience with IDE
tapes. You probably are better off trying this in -questions. If you
take a swing there, make sure to add information about which version
of FreeBSD you are running. Also, can you access the tape alright with
other commands like tar or dd?
