Problème de gravure de donnée

Bonjour,
J'ai un petit problème de gravure, j'ai avheté des CD-R bon marché ou il est marqué 52x speed mais impossible de graver ac tous les programmes

mon graveur supportant un vitesse maximum de 48x il me grave alors a 32 fois.

lorsque la gravure est terminée mon pc me dit qu'il a été gravé avec succes alors que lorsque je le lit il n'y a absolument rien dessus et mon cd est foutu.

j'ai enregistrer le raport de gravage et le voici:
