Playing With ISO File

An ISO file, often called an ISO image is an "image" of an entire CD, DVD, or BD. The entire contents of a disc can be perfectly represented in a single ISO file. An ISO image is an archive file of an optical disc, composed of the data contents of every written sector of an optical disc, including the optical disc file system. When using an ISO file you have three options:

Copy it to a CD/DVD
Mount it to a 'Virtual CD/DVD Drive'
Extract the contents of it to your hard-drive

In this post, i will show how to create an iso of a CD/DVD rom and also to burn a CD/DVD using an ISO image in linux.

CREATE AN ISO OF A CD OR DVD.

Insert the CD or DVD whose image is to be taken.
Do not mount the CD/DVD. You can check if its already mounted using the command mount. Som linux versions have auto mount which automatically mounts CD/DVD.
# mount

If the CD is mounted please unmount it.

# umount /dev/cd--rom  or  # umount /mount/cdrom

Now the final step, create iso by using the dd command.

# dd if=/dev/cd--rom of=/tmp/cdimage.iso

In the above command,

if=source --> /dev/xxx

of=destination  --> file name of ISO

                                                                                     

BURN ISO TO CD.

Requirement: Need a cd rom attached to the system and a plain cd .. lol

First step is to find the inquiry strings of the CD ROM. You can find it by giving the command below:

# cdrecord -scanbus

From the output of the above command find the line similar to this. This depends on the type of cd rom attached your pc.

1,0,0 100) 'LG' 'CD-Writer' '1.0g'

Hence the inquiry string of your device is 1,0,0.

Now we can use the cdrecord command to burn the disk.

# cdrecord -v -dao dev=1,0,0 file.iso

If you need to specify the burning speed then modeify the above command.

# cdrecord -v -dao dev=1,0,0 speed=16 file.iso
