Thank-you Vulpes and Chuck; the atapicam mechanism looks like a fine idea.
However,
I am having problems getting it to work for me...

O.K. I am running FreeBSD 4.9. I built a new kernel with:

device          ata0    at isa? port IO_WD1 irq 14
device          ata1    at isa? port IO_WD2 irq 15
device          ata
device          atadisk                 # ATA disk drives
#device         atapicd                 # ATAPI CDROM drives
#device         atapifd                 # ATAPI floppy drives
#device         atapist                 # ATAPI tape drives
device          atapicam                # CAM device
device          scbus                   # Needed for CAM device
device          pass                    # Needed to connect scsi to cam
device          cd                      # SCSI cd connected through CAM
device
options         ATA_STATIC_ID           # Static device numbering

Some output from dmesg:

The cd1 is an _NEC DVD+RW ND-1100A. It is connected as a slave to the HP
CD-Writer
that is the master on the second IDE channel.

I have installed growisofs and cdrtools. cdrecord version is 2.00.3.
I can mount CDs on both cd0 and cd1. I can record CDs with cdrecord on cd0,
BUT I cannot record DVDs on cd1.

I am using Memorex DVD-Rs. Rated at 4.7GB on the label.

When I execute growisofs with one of these DVD-Rs in it I get:

> growisofs -dvd-compat -Z /dev/cd1c=nycity.iso
:-( unable to open("/dev/cd1c",O_RDONLY): Device not configured

However, I can mount CDs on it. It looks as though growisofs thinks that the
device is read-only.

Any advice would be greatly appreciated; I was hoping to use this DVD
setup as
a back-up media as tapes are getting expensive.
