On Linux? Did you use mt compression or did you call ioctl directly?

Thanks, I'll check it out.

0.5b (what I have now) manpage says the same thing. I tried
mt compression and mt setdensity first without any obvious success
so I was figuring to try ioctl next. I'm expecting I'll be able to
detect success or failure from the output of mt status. Is this
reasonable?
