CD writing on Fedora Core 3

I’m now thing of moving off Fedora Core 3 (probably to Ubuntu, or maybe FC4 for the Java stuff) and it turns out I’ve never written a CD from it, because when I tried it didn’t work: I kept getting the message “cdrecord: Success. Cannot open SCSI driver.” I finally managed to find a solution. For some reason I need to do this:

cdrecord dev=ATA:1,1,0 -eject -v speed=2 ubuntu-5.04-live-i386.iso

Note the ATA: in the dev bit. No idea why.
