je ne peux plus acceder a mon graveur dvd

Pour poster en français, il est préférable d'aller sur http://forum.ubuntu-fr.org/
Pourrais-tu poster /etc/fstab.

# /etc/fstab: static file system information.
#
# Use 'blkid -o value -s UUID' to print the universally unique identifier
# for a device; this may be used with UUID= as a more robust way to name
# devices that works even if disks are added and removed. See fstab(5).

J'ai lu le contunu du dossier /media durant l'insertion d'un CD. Voci ce que j'obtiens:

Peux-tu poster le résultat final.

j'ai toujours le meme resultat avec ou sans cd dans mon lecteur dvd ... :(

Pourrais-tu fournir le résultat des commandes:
   uname -a
   ls -l /etc/udev/rules.d
   cat /etc/udev/rules.d/70-persistent-cd.rules

2011-11-08 00:39 70-persistent-cd.rules Ce fichier a été modifié mardi 8.
Chez moi le samedi 5 novembre, probablement à l'occasion d'une mise à jour du système.

Dans ma configuration, je n'ai qu'un seul bloc à l'addresse pci-0000:00:0e.0-scsi-1:0:0:0.
As-tu un graveur externe ? As-tu changé la configuration hardware du PC ?

J'ai lancé un
    sudo udevadm monitor
mais à ma surprise l'insertion d'un CD ne provoque pas d'évènement udev. Idem pour
    sudo udisks --monitor.

Pour l'instant, je patauge...

salut
hier j'ai installer mon graveur dans un pc windose xp a un ami
et malheureusement le système l'a détectée mais je ne peux pas lire un cd ou dvd
donc je suis désolé de t'avoir déranger mais je crois que mon graveur a rendu l’âme
donc je vais terminer ce poste merci BEAUCOUP pour ton aide et ta patiences

... :(
