Hi, I got the following errors when I tried to burn a CD with my DVD/CD burner by using cdrecord command. >From the error messages, I have the following questions: 1) What actually is the root cause of these errors and how to fix it? 2) Is there any new version of cdrecord that can support my device and how can I get it? 3) Is there any other tool that can be used to burn a CD with my device? Thanks for your help. --david le. ------------------------------------------------ [root@x1-6-00-0c-6e-63-30-82 dreamcast]# !49 ./roast.sh kernel-boot.bin Cdrecord-Clone 2.01a19 (i686-redhat-linux-gnu) Copyright (C) 1995-2003 Jï¿¿rg Schilling scsidev: '0,0,0' scsibus: 0 target: 0 lun: 0 Linux sg driver version: 3.1.25 Using libscg version 'schily-0.7' cdrecord: Warning: using inofficial libscg transport code version (schily - Red Hat-scsi-linux-sg.c-1.75-RH '@(#)scsi-linux-sg.c 1.75 02/10/21 Copyright 1997 J.
