Graver sans ide-scsi
Salut,
Depuis peu, cdrecord permet d'utiliser les graveurs ATAPI sans passer
par la case « émulation SCSI ». Histoire d'essayer la chose, je suis allé
emprunter un graveur à la boutique du coin. Dans la foulée, j'ai
rétroporté vers Woody (1) le paquet cdrecord de Sid, qui donc
inclus le support direct de l'interface ATA. C'est paartiii...
On regarde d'abord si le graveur est reconnu :
cdrecord -scanbus -dev=ATAPI
scsidev: 'ATAPI'
devname: 'ATAPI'
scsibus: -2 target: -2 lun: -2
Warning: Using ATA Packet interface.
Warning: The related libscg interface code is in pre alpha.
Warning: There may be fatal problems.

Si oui, on peut essayer de lancer la gravure (j'ai tout de même fait un
test préalable avec l'option -dummy) :
cdrecord -dev=ATAPI:0,0,0 [OPTIONS]
scsidev: 'ATAPI:0,0,0'
devname: 'ATAPI'

Comme on peut le voir, ça a marché, et du premier coup !
En somme, rien de compliqué. Néanmoins, soyez PRUDENTS si vous
tentez l'expérience, le support pour l'interface ATA est encore
considéré comme alpha, c'est à dire pas forcément très stable...
