Re: Pas clair..

Salut!!
merci pour vos réponses.
A moi de préciser un peu plus le truc :
je fais un lsmod, apres avoir fait modprobe sd_mode

# lsmod
Module Size Used by
isofs 37112 0
sd_mod 15376 0
sg 27676 0

ntfs 186420 1
ide_cd 42464 0
cdrom 40988 1 ide_cd
rtc 12664 0

et le lsusb donne :

# lsusb
Bus 004 Device 001: ID 0000:0000
Bus 003 Device 001: ID 0000:0000
Bus 002 Device 001: ID 0000:0000
Bus 001 Device 002: ID 05e3:0701 Genesys Logic, Inc. USB 2.0 IDE Adapter
Bus 001 Device 001: ID 0000:0000

en fait, c est bien car le dvd rom est relié par ce Genesys logic en question
De plus, j ai regardé le dmesg encore une fois, et il dit :

voilà, alors moi je pense que c'est dans sg0 ou scsi0 (pas de pot ca existe pas scsi0)
je refais mon mount habituel

#mount -t iso9660 /dev/sg0 /mnt/dvdrom/
mount: /dev/sg0 is not a block device

avec sda non plus

alors je vais chercher growisofs car je trouve pas le paquet debian
je decompresse le dvd+rw tools et lance growisofs :

# ./growisofs -Z /dev/sda -R -J /mnt/dvdrom
:-( unable to open64("/dev/sda",O_RDONLY): No such device or address

ok, alors avec sg0 :

# ./growisofs -Z /dev/sg0 -R -J /mnt/dvdrom
Executing 'mkisofs -R -J /mnt/dvdrom | builtin_dd of=/dev/sg0 obs=32k seek=0'

voili voila, toujours ce k3b qui voit kedalles meme en lui disant de regarder /dev/sg0 (il dit ke ya rien qui marche dessus)

J espere que j ai été plus clair cette fois ci
merci encore
