Playing with Images
=====================

Creating An Image Copy Of A CD-ROM
----------------------------------

If we want to make an iso image of an existing CD-ROM, we can use dd to read all the
data blocks off the CD-ROM and copy them to a local file. Say we had an Ubuntu CD
and we wanted to make an iso file that we could later use to make more copies. After in-
serting the CD and determining its device name (we’ll assume /dev/cdrom), we can
make the iso file like so:

Example:

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

pankaj@pankaj-Satellite-C850 ~ $ sudo dd status=progress if=/dev/sr0 of=/home/pankaj/pank.iso
1407048+0 records in
1407048+0 records out
720408576 bytes (720 MB, 687 MiB) copied, 139.587 s, 5.2 MB/s
pankaj@pankaj-Satellite-C850 ~ $ 

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



Writing CD-ROM Images
---------------------

After we have an image file, we can burn it onto our optical media.

To write an image, we will use a tool named  as wodim, specifying the name of the 
optical media writer device and the name of the image file:

wodim dev=/dev/cdrw image.iso
