Brasero en Fedora 15, me ha vuelto inservibles varios discos cdr y/o dvd,
entonces, con wodim evitamos que gnome3 intervenga.
Antiguamente utilizábamos cdrecord, hoy es asi:
[root@larry ~]# wodim –scanbus
scsibus1:
1,0,0 100) ‘HL-DT-ST’ ‘DVDRAM GT30N ‘ ‘AS02′ Removable CD-ROM
[...]
scsibus4:
4,0,0 400) ‘TSSTcorp’ ‘CDDVDW SE-S084D ‘ ‘TS01′ Removable CD-ROM
4,1,0 401) *
[...]
Bueno, tengo la unidad física y una por USB (la que voy a usar).
Pero la tendría que referenciar como dev=4,0,0. pero por que?
tenemos la presencia de dm-mapper. ok.
[root@larry ~]# wodim –devices

Bingo, le pego a /dev/scd1, entrego opciones a gusto del consumidor y la ruta a la iso que queremos grabar y ya.

Me parece que el proceso de grabación fue mucho más rápido con esta utilidad,
se la recomiendo.
Adelante estudios.
