You need two programs for this : cdrecord and mkisofs (They are by default installed on my Ubuntu)

First step, you need to identify your CD driver :

cdrecord -scanbus

Remind the 3 first number (for me : 1,0,0)
Second step, create the .iso :

mkisofs -v -r -J -o image.iso /home/d/copie

Some explications :

  • -v is for verbose mode
  • -r gives the right to zero. For example if you create your CD as root, without this command, only the user "root" can use the files. But with -r every user who mount the CD can use the files.
  • -J is the Joliet. It is for supporting the long name of your image. It is very useful when you use the CD on Windows.
  • -o for output. Write the name of your .iso after this.
    %%

Third step, burn the image on your CD :

cdrecord -v speed=48 dev=1,0,0 -data image.iso

Wait until your CD is completly burn, and then :

eject

I hope this could be help someone, but it's a good reminder for me, that is the first purpose of this section !
