Paul, The -e made a huge difference in runtime.
For what its worth, here is the result I received. # date ; amtapetype -e 400g -f /dev/rmt/3n ; date Wed May 24 09:23:58 EDT 2006 Writing 2048 Mbyte compresseable data: 33 sec Writing 2048 Mbyte uncompresseable data: 33 sec Estimated time to write 2 * 409600 Mbyte: 912 sec = 0 h 15 min wrote 12386304 32Kb blocks in 189 files in 6539 seconds (short write) define tapetype unknown-tapetype { comment "just produced by tapetype prog (hardware compression off)" length 386048 mbytes filemark 0 kbytes speed 61853 kps } Wed May 24 13:01:08 EDT 2006 3 1/2 hours, the previous attempt ran overnight and was not where near complete. I really should run it again with HW compresson ON.
