You know, it actually works so long as the LBA value is greater than 0... for instance, if I burn a 300 block data track (mode 1), the LBA for the disk is then 66. I can burn raw mode tracks after that. I've not looked closely enough at it yet to see what value the drive considers "illegal" but it'd be nice if it was just some faulty mathematics somewhere :) > >I don't think there are any alternatives, either... cdrecord and cdrdao > >both support the LG CED-8080B, but, I know the former won't work since > >there's not ATAPI passthrough and I believe the latter suffers the same > >fate... > > 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.

I should go through and compare the method cdrecord users with the FreeBSD ATA drivers. Of course, I'm just a Perl hippie so that's not as easy as it sounds ;) Erik. -- E. L.
