How to create ISO image from CD/DVD

Create ISO image from CD/DVD through command mode
=================================================
1. Steps to follow
----------------------------
(I).Create an ISO image from optical media
In this example, we're going to copy the contents of a disk in the CD/DVD drive (/dev/cdrom) to an ISO image file. Open a terminal window and type the following at the command line.

#dd if=/dev/cdrom of=/directory/example.iso

Notations:
- dd is the program used to convert and copy a file.
- if defines an input file.
- of defines an output file.
- iso is the resulting ISO image file.

(II).Create an ISO image from files in a directory
To create an ISO image from files within a directory is just as simple. State an output directory and name of the ISO to create, along with a source directory. For example:

#mkisofs -o /home/linuxlookup/example.iso /source/directory/

2. Steps to follow

-------------------

 Linux makes it easy to create an ISO image from your CD or DVD.

1. Insert the CD or DVD that you want to make an ISO image of.

2. Open a terminal window.

3. Execute the following command:

#cat /dev/scd0 > /home/shamanstears/test.iso

where /dev/scd0 is the device name for your drive (to find this, go to the Main Menu, click on System, mouseover Administration and select System Monitor. Click the File Systems tab. The device name will be listed in the Device column). Also make sure to change the path and iso filename to the desired path and filename.

The disc will begin to spin and the ISO image will start being constructed. Once it has completed, you have an ISO image of your CD. To verify that the image was properly created, mount the ISO file and check the contents.
