To use your cd-writer to burn cd's, you had to enable scsi emulation in yor kernel. Did you?

Look around on this forum, you'll find alot of threads about. For example this one

Do you have "hdx=ide-scsi" in menu.lst/lilo?
did you change the device in fstab?
are the modules loaded?
what gives "cdrecord --scanbus"?

girafon · Posted: Sat Aug 31, 2002 9:09 am Post subject:

i dont use lilo but grub
fstab :

/dev/ROOT / reiserfs noatime 0 0
/dev/SWAP none swap sw 0 0
/dev/hda1 /mnt/win vfat auto,rw 0 0
/dev/cdroms/cdrom0 /mnt/cdrom iso9660 noauto,ro 0 0
/dev/cdroms/cdrom1 /mnt/graveur iso9660 noauto,ro 0 0
/dev/floppy/0 /mnt/floppy vfat noauto,rw 0 0
proc /proc proc defaults 0 0

yes modules are loaded.

and cdrecord --scanbus give that :
Cdrecord 1.11a30 (i686-pc-linux-gnu) Copyright (C) 1995-2002 Jörg Schilling
cdrecord: No such file or directory. Cannot open '/dev/pg*'. Cannot open SCSI driver.
cdrecord: For possible targets try 'cdrecord -scanbus'. Make sure you are root.

help!
thanx

Your cdrom(burner) device should be something like: /dev/sr0
you're still using the ide device
and what is dev/ROOT /dev/SWAP? shouldn't it be /dev/hdaX

biroed · Posted: Sat Aug 31, 2002 9:29 am Post subject:

maybe you can find the device with dmesg

i ve no sr* in /dev

ive a empty /dev/scsi directory

please help!
thanx

you dont see something like:

SCSI subsystem driver Revision: 1.00
scsi0 : SCSI host adapter emulation for IDE ATAPI devices
Vendor: PHILIPS Model: PCRW804 Rev: 2.0
Type: CD-ROM ANSI SCSI revision: 02
Attached scsi CD-ROM sr0 at scsi0, channel 0, id 0, lun 0
sr0: scsi3-mmc drive: 32x/32x writer cd/rw xa/form2 cdda tray

btw did you also compiled
scsi disk support
scsi generic support in the kernel

Make sure you did NOT compile in support for an IDE CD-ROM. Otherwise it will "see" the CD drive first, and the SCSI driver won't.

No IDE CD-ROM
Yes to SCSI Emulation
Yes to SCSI
Yes to SCSI Generic (for burning)
Yes to SCSI CD-ROM (for access)

but i ve another ide CDrom...
dont i need IDE support for this one??

biroed · Posted: Sat Aug 31, 2002 11:10 am Post subject:

You could give your 2nd drive also scsi emulation, but since it don't work
it's not an option...

girafon · Posted: Sat Aug 31, 2002 11:18 am Post subject:

im lost
what must i do?

biroed · Posted: Sat Aug 31, 2002 11:44 am Post subject:

i assume you try the things mentioned in this thread, then maybe your device isn't supported.
Anyway you should read the cdwriting howto for more details

girafon · Posted: Sat Aug 31, 2002 2:29 pm Post subject:

ok i remove ide CD support in my kernel and it works
thanx guys

girafon · Posted: Sat Aug 31, 2002 2:53 pm Post subject: a last thing...

can somebody give me his/her fstab (for scsi CD).
cause now i cant mount any CD any more

biroed · Posted: Sat Aug 31, 2002 2:59 pm Post subject:

/dev/sr0 /mnt/cdrom iso9660 users,noauto,ro 0 0

you can still use the IDE drivers for your other cd-rom, just make sure you have an

options ide-cd ignore='hdX' # hdX = your cd-writer, e.g. hdc

entry in your /etc/modules.conf -- the IDE driver will ignore your cd writer and the scsi emulation drivers can take care of it.

ok i try your line but,

bash-2.05a# mount /mnt/graveur/
mount: wrong fs type, bad option, bad superblock on /dev/sr1,
or too many mounted file systems

bash-2.05a# mount /dev/sr1 /mnt/graveur/
/dev/sr1: Input/output error
mount: block device /dev/sr1 is write-protected, mounting read-only
/dev/sr1: Input/output error
mount: you must specify the filesystem type

my fstab is the same as yours...
any clues?

thanx inukshuk.

girafon · Posted: Sat Aug 31, 2002 3:19 pm Post subject:

my fstab is exactly that :
/dev/sr0 /mnt/cdrom/ iso9660 ro,noauto,user 0 0
/dev/sr1 /mnt/graveur/ iso9660 ro,noauto,user 0 0

why doesnt it work???

inukshuk · Posted: Sat Aug 31, 2002 3:26 pm Post subject:

uhm... what is the output of:

ls -l /dev/sr0

and

ls -l /dev/sr1

?
