    Pareil, d'autant plus qu'un recherche sur google donne des pistes ... mais bon t'a déjà sûrement tout testé depuis le temps.

    Mais comme t'a dit que les RTFM t'en avait ta claque je te propose un STFW :)

    L'english te pose-t-il un problème ?

    allez, sans rancune mais d'une manière générale quand on demande de l'aide le mieux c'est d'être sympa ...

    First, I wanted to test that multisession writing is possible from my Lenovo external DVD unit, so from the command line I execute the following statement to burn two 1 Gb files on the first session of the disc. This is a DVD-R unbranded disc bought from a supermarket.

    growisofs -speed=1 -Z /dev/sr0 -R -J /data/isos/linux_11gR2_database_1of2.zip /data/isos/linux_11gR2_database_2of2.zip

    Parameters explained

    -speed=1 This is the most reliable setting

    -Z initialize DVD as this is the first session

    -R -J for increased compatibility with Windows using the Rockridge and Joliet extensions

    After the DVD is ejected, it can be insterted again. I used an additional command to verify that ZIP files are generated correctly.

    It would also be a good idea to test it after one or two sessions from a Windows machine using the ‘verify’ command of the 7Zip application for example.

    Adding a second session to the DVD requires a different parameter (-M)

    growisofs -speed=1 -M /dev/sr0 -R -J /data/isos/RIPLinuX-6.3.iso

    and this is some of the expected output after a successful second session gets recorded.

    Executing 'genisoimage -C 16,1748352 -M /dev/fd/3 -R -J RIPLinuX-6.3.iso | builtin_dd of=/dev/sr0 obs=32k seek=109272'

    A word of warning: it cannot be guaranteed that all DVD writers will work in Linux. If you want to post here the combination of Linux distribution/hardware that worked for you, you are welcome to do it.
