Je viens de constater un truc bizarre : le graveur de CD de mon portable
peut graver en vitesse 10x. Or j'ai des CD qui supportent une vitesse de
52x qui ne sont gravés qu'en 4x. A quoi est-ce dû ? J'ai d'autres marques
de CD qui sont très bien passés en 10x...
Voici la sortie de cdrecord sur les disques qui posent problème
(duplication de CD que mes gamins ont eu à Noël, pour éviter qu'ils les
flinguent tout de suite !) :
