Gravure sur boitier externe

J'ai un graveur sur un boîtier externe USB/Firewire.
La gravure de DVD (growisofs) fonctionne très bien.
En revanche, la gravure de CD-RW et de CD ne fonctionne pas :



fabien@walhalla:~$ sudo cdrecord blank=fast dev=3,0,0 speed=1 -audio aniRigolo.iso/Track01.wav

cdrecord: No write mode specified.

cdrecord: Asuming -tao mode.

cdrecord: Future versions of cdrecord may have different drive dependent defaults.
