Would it be possible to use the scsi command? I think this will work: 1. Use the mode page editor to change the data bytes per physical sector to 512: "scsi -f /dev/rsd?.ctl -m 3 -e". At any rate, you'll see what the AS/400 has it set to. 2. Use the "scsiformat" script in -current to format the drive. -- Peter Dufault Real Time Machine Control and Simulation HD Associates, Inc.
