    I'm pretty sure there is a way to burn a cd with cdrecord without having to build an iso image first, I just want to put it into a shell script and make a nice and simple command :)

    Anyone managed to do this?

    I haven't tried this myself but I guess the following in theory would work if you have 2 cd drives. cdrecord can't do it by itself.

    dd if=/dev/cdrom2 bs=32k | cdrecord -v speed=x dev=n,n,n -

    shouldn't that be

    readcd dev=0,1 | cdrecord blah ?

    Well its a laptop so theres only 1 drive available; but what I mean is supplying a list of files or directories on the hard drive to cdrecord.

    Could I send the output of mkisofs to cdrecord using a pipe? (or named pipe?)

    What you mean like from man cdrecord

    mkisofs -R /master/tree | cdrecord blah
    ?

    I though you always need to make an image first ? eg say for a directory 'disk2' with a load of files:

    mkisofs -r -o ora9id2.iso Disk2/


    then burning it:

    cdrecord -v speed=10 dev=0,0 ora9id1.iso

    Hi, I've used this successfully.

    You can use 'dd' to make an iso image from a CD, so you can consider them identical, so nothing stopping you from telling cdrecord to use a disc as a track.
    The problem is the iso filesystem size is generated slightly incorrectly.

    cdrecord offers an isosize option which tells it to use the iso9660 filesystem size given as the size of this track.

    What that means is you can use:

    cdrecord driveropts=burnfree -v speed=4 dev=02,03,00 -eject -isosize /dev/scd2

    (remembering to change device numbers for your own system) to copy your CD.


    I have only used this on a system where both reader and writer were SCSI.
    IDE devices have much more overhead, but with burnfree on, it should work fine.
    I've never burned it faster than 4 speed.
    It won't work on multi-session discs.
    It will probably not work on CD-RW discs created with packet writinig software. (udf)
    It won't work for audio discs as they're not iso9660 either. ww)
