Jon, you are exactly right, and I was... not. :-) In my (meager) defense, I did also mention "tape-vendor-supplied st.conf default", and for example, the Quantum DLT/Solaris recommendation is: From: http://www.quantum.com/AM/support/DLTtapeDrivesMedia/TechnicalDocuments/Default.htm Where the Solaris install PDF does explain all the funky mode bits, > If you are installing a DLT4000 add the following line: <DLTtape data> = 1, 0x38, 0, 0x8639, 4, 0x17, 0x18, 0x82, 0x83, 3; > If you are installing a DLT7000 add the following line: > <DLTtape data> = 1, 0x38, 0, 0x8639, 4, 0x82, 0x83, 0x84, 0x85, 3; > If you are installing a DLT8000 add the following line: > <DLTtape data> = 1, 0x38, 0, 0x8639, 4, 0x84, 0x85, 0x88, 0x89, 3; > If you are installing a Super DLTtape add the following line: > <DLTtape data> = 1, 0x38, 0, 0x8639, 4, 0x90, 0x91, 0x90, 0x91, 3; This is what I'm currently using for DLT, and it does default to max density/compression, FWIW. -- Jay Lessert [EMAIL PROTECTED] Accelerant Networks Inc.
