Voilà ce que je fais exactement:
=>Je créé l'image ISO de mon DVD original:
dd if=/dev/sr0 of=backup.iso
=>Je formate mon DVD+RW:
dvd+rw-format /dev/sr0
=>Je grave mon image:
cdrecord -v -dev=0,0,0 -data backup.iso

Et voilà ce qui se passe:
=>Je créé l'image ISO de mon DVD original:
dd if=/dev/sr0 of=backup.iso
dd: lecture `/dev/sr0': Erreur d'entrée/sortie
139408+0 enregistrements lus.
139408+0 enregistrements écrits.
=>Je formate mon DVD+RW(cette fois là j'avais deja formatté le DVD+RW):
Samson:/home/yugiohjcj# dvd+rw-format /dev/sr0
* DVD+RW format utility by <appro@fy.chalmers.se>, version 2.0.
* 4.7GB DVD+RW media detected.
- media is already formatted, lead-out is currently at
4590208 KB which is 100.0% of total capacity.
- you have the option to rerun with -f flag to enforce
new format (not recommended).

Comme vous pouvez le voir il y a une erreur d'entrée sortie lors de la création de l'image ISO. Pourquoi?

Bien sûr, le DVD+RW gravé ne passe pas sous ogle parce qu'il a été mal gravé et la gravure a duré que quelques secondes car au départ, c l ISO qui est mauvais.
Aidez-moi SVP.
