Une fois sur 2 ça marche, j'explique:
La première fois échec, le cd était dans le graveur au démarrage, et j'obtiens le commentaire /dev/hdc busy (cf.1er prompt).
La seconde fois, j'ai tapé la commande sans l'envoyer (pas de validation Entrée), j'ai éjecté le CDRW et l'ai rechargé immédiatement. La manip tourne avec succés (cf 2ème prompt), je suppose que "les périphériques blocs" comme mon lecteur et mon graveur sont monté automatiquement (non compatible avec k3B et même Xcdroast 0.98alpha15)/ ou sollicité en permanence d'ou "device busy ".
Quel peut être la cause d'un tel comportement?
