I’ve been asked how to extract an iso image from a cd. While there are a few approaches, one is the clean and easy way and that’s the readom way.

• Insert your cd into the drive. If Ubuntu mounts the drive, umnount it
  (umount /media/xxx)
• Using readom (read only memory), we specify the source device and the target file
  (readom dev=/dev/yourcdrom f=/home/user/directory/imagename.iso)

Your drive should spin up and create the iso. Once finished, mount the iso and test it.

That’s it. Happy rippin!
