Hi.  I'm following the CD-Writing HOWTO in the hopes of getting my
CD burner to work.  I tried the script "Testing for drivers" given
in the HOWTO, and this is the output:

  # . test4drivers
  cdrecord: No such file or directory. Cannot open SCSI driver.
  cdrecord: For possible targets try 'cdrecord -scanbus'. Make sure you are root.

  Ensure the module sr_mod is loaded automatically next time.
  Using /lib/modules/2.4.18-686/kernel/drivers/scsi/sr_mod.o
  Ensure the module loop is loaded automatically next time.
  Using /lib/modules/2.4.18-686/kernel/drivers/block/loop.o
  The following is only needed for IDE/ATAPI CD-writers.
  Ensure the module ide-scsi is loaded automatically next time.

  cdrecord: No such file or directory. Cannot open SCSI driver.
  cdrecord: For possible targets try 'cdrecord -scanbus'. Make sure you are root.

(The lines beginning with "Using" are generated by calls to insmod.)

I am at a loss at this point, since the HOWTO does not discuss what
to do in case of this outcome.  My system is:

  # uname -a
  Linux luna 2.4.18-686 #1 Sun Apr 14 11:32:47 EST 2002 i686 unknown

My distro is Debian (Woody).  I wish I could report what kind of
CD-RW drive I have, but my laptop's documentation says little on
the subject (FWIW, the machine is a Toshiba Satellite 1905-S301).
All I know is that it is a "DVD/CD-RW multifunction drive."  (How
can I find more about this drive?)

Any advice on moving this forward would be much appreciated.

OK, I found out that it's a Toshiba DVD-ROM SD-R2212.

bill

OK.  That doesn't appear to be a CDR-RW capable device, though.

Hi,

Bill, do you have scsi emulation in your kernel? If so then pass
"hdc#=ide-scsi" to the kernel.  If you don't have scsi emulation you must
enable it as a module and compile the new kernel. After you reboot the
system, then you can test your cdrw device with 'cdrecord - scanbus'. The
device lun will be displayed with the 'cdrecord - scanbus'.

You should look at;

The magic is in the Magician not the wand!

Hi,
        according to google, the SD-R2212 is a combd DVD / CD-RW, so it should
work.  What you need to do to get it working is find out which IDE device
it is connected to, so lets assume hdb.  Then add the parameter
'hdb=ide-scsi' to your kernel boot line in LILO or Grub or whatever
bootloader you use.  The basic problem is that by default, it will be
detected as an IDE CD device.  To use it as a CD writer, you have to make
Linux think it is a scsi device.  The easiest way, without re-compiling
the kernel, is to add the above parameter to the kernel at boot time.
Once this is done, ensure that the apropriate modules are loaded, and then
'cdrecord -scanbus' should detect your device.

Thank you all very much!  Thanks to your advice, I got cdrecord
-scanbus to yield the right output and managed to burn a CD,
apparently without difficulty (stress on "apparently").

That's the good news.  The bad news is that I cannot mount the
newly burnt CD.  I get:

# mount /cdrom
mount: wrong fs type, bad option, bad superblock on /dev/cdrom,
       or too many mounted file systems
# mount -t iso9660 /dev/scd0 /cdrom
mount: block device /dev/scd0 is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/scd0,
       or too many mounted file systems

The problem has to do with the burning, because both commands above
work fine if I have a known OK cd (e.g. a Debian distribution disk)
in the drive.

Any ideas on what could be going wrong?

Again, many thanks!

I did it again: I neglected to included important info in my last
post.  Here it is:

To make the image, I did:

  # mkisofs -r -J -o /tmp/cd_image /usr/local /root /etc /var

I checked the image with

  # mount -t iso9660 -o ro,loop=/dev/loop0 /tmp/cd_image /cdrom

Everything OK.  Next I burned the CD:

  # cdrecord -v speed=2 dev=0,0,0 -data /tmp/cd_image

This proceeded without errors.  Problems began when I tried to
mount the newly burned cdrom, as described in my previous post...

b.

All's working now.  I just needed to eject the newly-burned CDs at
least once before trying to mount them.  Curious.

Once more, thank you all for the help.

bill

All Windows burning software that I'm familiar with ejects the CD-R upon
completion of the burn.  My observations show that when a CD is inserted
the activity LED comes on.  I believe the OS is reading and processing some
information from the CD.  TOC?
