This is under FreeBSD 3.1-RELEASE. FWIW, I have a similar situation. One box has a Sony SDT-5000, which was happily writing 4GB or more with FreeBSD 2.2.8, and which now refuses to write more than 1.5GB. Another box has an HP 1533 which continues to write 4GB plus. > Doug White suggested I use -B and/or -b flags to indicate tape length.

That might be worth trying, if you're not terribly bothered about 60/90m tapes. I've been trying to get the jumper settings for my SDT-5000 for weeks, but nobody seems to have them. :-( Ian.
