	Hola. Muchas gracias por responder.


	Al hacer eso, obtengo lo siguiente:

$ sudo cdrecord -checkdrive driveropts=help dev=/dev/hdc

	Da un warning de que tengo un kernel superior al 2.4... pero ya tenía
el 2.6.8 con warty, así que espero que no sea eso.

	No sé por qué me dice que no puede abrir /dev/hdc, ya que lo tengo
montado en /media/cdrom0, y lo montó el ubuntu solito...

	¿alguna sugerencia?

	Gracias por adelantado.

	Un saludo,
