Joerg Wunsch committed a "scsiformat" script to do a scsi disk format based on the same command. Your command will format the drive. You'll have to set the command timeout to a longer time using the "-s" switch since the format will take a while. You can fetch the script from -current if you want to refer to it. It appears that after a command times out the system is panicing. No, it shouldn't panic, and I don't think it used to. Peter
