Burn CD/DVD since terminal

Fuente: http://blogofsysadmins.com/grabar-cddvd-en-consola-con-mkisofs-y-cdrecord

Primero averiguar en qué dev está la unidad de cd:

cdrecord -scanbus

Luego usar el comando:

cdrecord -v dev=4,0,0 speed=10 isofile.iso

Cambiar dev=4,0,0 por dev=1,0,0 ó 2,0,0 ó 3,0,0, según el valor conseguido con cdrecord -scanbus

I looked for that because in my Lucid Lynx didn’t worked Brasero with the kernel 2.6.38. But since terminal it was possible to burn DVDs

Este pequeño tutorial fue probado en CentOS 5 pero funciona para cualquier versión de Linux, al final la consola es igual para todos.

Para quemar en consola, necesitamos contar con una quemadora de CD/DVD, Bastantes CD/DVD donde quemar, lo que queremos quemar y los siguiente programas que instalamos a continuación.

# yum -y install mkisofs cdrecord

Necesitamos crear una .ISO de lo que deseamos quemar. para esto utilizamos el comando mkisofs

# mkisofs -r -l -o imagen_que_quiero_crear.iso /home/data_que_quiero_quemar

Mas o menos nos saldrá la siguiente información

Antes de proceder a quemar primero necesitamos identificar el dispositivo (en este caso la quemadora) entonces escaneamos el dispositivo

# cdrecord -scanbus

Linux sg driver version: 3.5.27
Using libscg version ‘schily-0.8′.
cdrecord: Warning: using inofficial libscg transport code version (schily – Red Hat-scsi-linux-sg.c-1.83-RH ‘@(#)scsi-linux-sg.c 1.83 04/05/20 Copyright 1997 J. Schilling’).

Con esto podemos notar que nuestra quemadora esta identificada en 4,0,0 400) ‘HL-DT-ST’ ‘DVD-RAM GSA-H55N’ ’1.02′ Removable CD-ROM

Procedemos al quemamos, donde en la opción dev=xxx devemos indicar en identificador de nuestra quemadora, que en el paso anterior salio.
