Did you try cdrecord dev=help like it says? The output of that will
tell you that -scanbus isn't supported with ATAPI devices. I got it
to work blind using 'cdrecord speed=8 dev=ATAPI:0,1,0 -v my.iso' for
a CD-RW at hdb. So, I'm assuming the first 0 is the IDE channel,
the 1 is for a slave (so 0 for master?), and the third I'll just leave
as zero. Of course, don't use the ide-scsi module. Use the ide-cd
module instead.

Hope this helps,

Andy Johnson
