Each drive has specific media it can read, write and rewrite. A CDRW drive cannot write on DVD media. You would need a DVD writer - and then of course it would depend on the media that the writer says it can write on. But I'd guess that you can use a CDRW disk as a UDF partition and not have to worry about cdrecord or anything else - just mount it and use it as any other partition (but much slower - and dont do LOTS of update) The point I meant to make (but didn't do very well) was that RedHat9 - out of the box - will now use a DVD-RAM drive with a UDF formatted DVD-RAM disk just like a HDD. I follow this to also mean that you should be able to get any other rewitable drive to work with UDF as a mounted partiton as long as the media is correct for the drive. I'm using my DVD-RAM disks as rsync backups of important data. -- -Cheers -Andrew MS ... if only he hadn't been hang gliding!
