According to this, the ide-cd module is also loaded, and maybe has been
loaded before ide-scsi. If you use a module-only configuration
(ide-scsi and ide-cd as modules), you can do the following:
rmmod ide-cd
rmmod ide-scsi
modprobe ide-cd ignore=yourcdwriterhere
modprobe ide-scsi
If the ide-cd driver is loaded before ide-scsi, and nothing tells it
which devices to ignore, it will access all ide cdroms, and ide-scsi,
if loaded later, won't. If it does, configure some file in
/etc/modutils to contain the line
options ide-cd ignore=yourcdwriterhere
and run update-modules to ave your changes to /etc/modules.conf.
If it still doesn't work, give us more information, including:
the append line of your bootloader
the output of dmesg | grep command
the output of dmesg | grep ide-scsi
the output of dmesg | grep ide-cd
all lines from /etc/modules.conf regarding ide-cd and ide-scsi

Don't change /etc/modules.conf directly. Its content is generated by
update-modules from the files in /etc/modutils. Edit them instead. Or
create your own file in /etc/modutils.

Well, this seems to verify that all your drives are accessed by the
ide-cd driver. cdrecord has experimental support for writing without
ide-scsi emulation, but I never tried it and don't know if it is
reliable.
Also /maybe/ cdrdao does not work because it doesn't have permissions to
access the ide device files which belong to the disk group (at least,
if cdrdao isn't suid root). You could try to change ownership from
root.disk to root.cdrom for your cd writer device file (but _not_ for
your hard disk). And /don't/ add yourself to the disk group. However, I
thik the preferred way still is to use ide-scsi emulation, at least
with 2.4 Kernels.
