I've > tried the obvious: Hi. We're running a Sony SDT-7000 DDS-2 tape drive, which (if I recall correctly) is the same drive, but with a faster transport. In our drive, we use 120 meter DDS-2 tapes, and we get 4 gigs uncompressed, and 8 compressed (about 6 gigs in real-world use) using Amanda (and software compression, rather than hardware compression). This doesn't really answer your question, but it might be helpful. Cheers, Ed. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hardware" in the body of the message
