It is in the ATA kernel code, or rather (IMHO) the LG firmware not
behaving according to spec.  I took a quick look at what was going on,
but without proper hardware documentation thara isn't much to do; the
drive insists that a command is "illegal" and that's it...

Hence the purchase of a better drive.

Pretty much all other CD-RW programs have been written for SCSI, and
use some kind of scsi-to-atapi conversion library or driver to work
with atapi drives.  Whether atapi actually just is scsi commands over
a different transport or not I don't know, but FreeBSD for the time
being does not have such a compatibility thingie.
