I'm trying to obtain 'optimal' settings for a Seagate DDS-3 drive, ARCHIVE Python 04106-XXX 715G. Kernel (2.2.6, btw) sez: ahc0:A:6: refuses WIDE negotiation. Using 8bit transfers (ahc0:6:0): "ARCHIVE Python 04106-XXX 715G" type 1 removable SCSI 2 'mt -f /dev/rst0 status' sez: Present Mode: Density = 0x25 Blocksize variable ---------available modes--------- Mode 0: Density = 0x00 Blocksize variable Mode 1: Density = X3.136-1986 Blocksize = 512 bytes Mode 2: Density = X3.39-1986 Blocksize variable Mode 3: Density = X3.54-1986 Blocksize variable I'm not finding any corresponding info for density = 0x25 on a man mt, nor do I find any corresponding values in <sys/mtio.h>. What to do? I'd like to have access to compressed devices, none of the modes appear relevant. I'm a little confused about where I should specify density values - and what values I should use. Is this enough info to get a coherent answer? Or am I omitting some vital info? And, does anyone know what bpi this device supports? Seagate's docs are, um, suboptimal. I scanned the mail archives and the FAQ/Handbook, to no avail. ------------------------------------------------------------------------------- Chris Faehl | Email: cfaehl@cs.unm.edu The University of New Mexico | URL: http://www.cs.unm.edu/~cfaehl Computer Science Dept., Rm.
