it looks like you have scsi emulation on for the ide drive. i dunno why you do, cause since you have real scsi no need to emulate ay.
i guess i would remove it and let it be normal, this means removing entry in lilo.conf or grub.conf and a reboot.
ln -s /dev/cdrom /dev/hdd
ln -s /dev/cdrom1 /dev/scd0
