Michel,
It seems to be saying that /media/cdrom is not a directory.
Perhaps you could show us "ls -l /media".

Also /dev/cdrom is probably a symlink to /dev/scd0, could
you confirm that?

cdrecord and the sg driver are finding the ATAPI writer ok
(as indicated by "cdrecord -scanbus") so I don't think 
there is a problem with your cd writer or sg.

And this is the output of tail -f /var/log/messages :

Note that before I do a modprobe sr_mod I received another error 
message, and when I loaded it, I see in logs :

What do you think of this mess ?
Thank you for your help, again ;-)

hello,
i use an IDE cdwrite with sg, and when thoses modules are loaded, 
cdrecord -scanbus works :
sg                     24036   0  (autoclean)
ide-scsi                7648   0  (autoclean)
scsi_mod               49804   2  (autoclean) [sg ide-scsi]
which produces :

Nice.
But to mount the cdrom i experience some problems. Note that i have :
- kernel 2.4.18
- cd support compiled as modules : scsi_mod, ide-scsi, sg, sr_mod, 
ide-cd, cdrom (all modules)
- only one cdwriter, no cdrom : /dev/hdc and no /dev/hdd

i.e. with find /proc/ide -type d -ls :
4307    0 dr-xr-xr-x   4 root     root            0 jui 29 00:51 /proc/ide/
4327    0 dr-xr-xr-x   3 root     root            0 jui 29 00:51 
/proc/ide/ide1
4332    0 dr-xr-xr-x   2 root     root            0 jui 29 00:51 
/proc/ide/ide1/hdc
4308    0 dr-xr-xr-x   4 root     root            0 jui 29 00:51 
/proc/ide/ide0
4320    0 dr-xr-xr-x   2 root     root            0 jui 29 00:51 
/proc/ide/ide0/hdb
4313    0 dr-xr-xr-x   2 root     root            0 jui 29 00:51 
/proc/ide/ide0/hda

and when i issue this command, i get an error :
bubus:/media # modprobe sr_mod
bubus:/media # mount /dev/cdrom /media/cdrom -t iso9660
mount : Périphérique de bloc/dev/cdrom est protégé en écriture. Montage

....

N'est pas un répertoire = Not a directory, in english
??? This trouble my knowledge of what's happening inside ;-(

I would like to understand ! Please help !
Thanks

    Michel
