Por ahora mi método requiere privilegios de superusuario (root) o el uso de sudo ya que el acceso al dispositivo así lo requiere.
Primero debe identificar el nombre de archivo que representa a su unidad DVD quemadora.
En un Fedora 5, con el que redacto esta nota, recuperé esa información con:
# dmesg | grep -i dvd
hdc: DVD DC DW1670, ATAPI CD/DVD-ROM drive
Entonces, para blanquear el dvd (o cd) rescribible:
$ su -
Password:
# cdrecord dev=/dev/hdc --blank=all
Hay otros métodos para blanquear y ello depende del soporte de su unidad. Puede saber más acerca de los métodos de blanqueo con man cdrecord.
Para quemar por ejemplo un iso, digamos el Fedora 7 Test4 hacemos (salida filtrada):
# cdrecord dev=/dev/hdc -v /home/gomix/f7-test4-i386/F-6.93-i386-DVD.iso
cdrecord: No write mode specified.
cdrecord: Asuming -tao mode.
cdrecord: Future versions of cdrecord may have different drive dependent defaults.
