Write more on your CD !!!

Bhullarz's Avatar author of Write more on your CD !!!
This is an article on Write more on your CD !!! in Unix.
Sometimes you must have noticed that you have 1gb of data to write. But you are unable to decide that what media should you use. Because 1 DVD can be more than enough required and 1 CD is not enough for writing the data. And if you use another CD, that would be probably half free. So, you will be confused that what to choose.

We all, have heard about NERO's feature OverBurn, under which NERO can write upto 10 MB extra data on your CD/DVD than its capacity. But have your ever heard that you can write upto 300 MB extra data on your 700 MB capacity CD?

Yes, It is possible. If you are using the Linux. Linux has such powerful features, which can make this happen. So, I hope till now, you will be knowing that what I am going to discuss in this article.

Before I start mentioning the steps, I would like to tell you that USE THIS TRICK COMPLETELY AT YOUR OWN RISK. Neither Go4Expert.com not I will be responsible for any kind of damage done to your system or Media.

Because I believe that Linux is very delicate system. Only the experts should handle it.

So lets start with the steps:
1. You need to download the following tools:

2 a. Compiling CDRTools:
unpack the .tar.gz
Code:
tar -xvzf cdrtools-beta.tar.gz
configure:
Code:
 ./configure -prefix=$HOME/cdrtools
(Replace prefix with anything you like)

compile and installs:
Code:
make && make install
2 b. Compiling CDRKit
unpack the .tar.gz
Code:
tar -xvzf cdrkit-current.tar.gz
configure:
Code:
cmake -DCMAKE_INSTALL_PREFIX=your/prefix.
compile and install
Code:
make && make install
3. Compiling zisofs-tools
Follow the same steps for zisofs-tools as did for CDRTOOLS, but do not specify a prefix.

Code:
MAN Pages for review:
    -mkzftree : www.man.cx/mkzftree
    -mkisofs : www.man.cx/mkisofs
    -genisoimage : www.man.cx/genisoimage
4. Creating CD/DVD
create a directory tree of cd in sperate directory
create another directory to hold compressed filesystem
mkdir $HOME/compcd
create compressed structure
mkzftree $HOME/cddir $HOME/compcd
Compressed disk structure is created and now lets compile the ISO image.
Switch to prefix/bin of CDRTools or CDRKit (whichever you are using)
use mkisofs or genisoimage respectively
genisoimage -R -z -o cd.iso $HOME/compcd
Burn the ISO image
Insert disk and mount
Change to mount directory and type ls-la for file listing
type df -ha
That's it.

Drawback of this technique is that, this kind of compilation would be readable by linux only and linux which is having latest kernel module.

If you're really that fussed about wasting space on a 23 pence* DVD-R then use a DVD RW so you can erase and start again. Or write to the DVD-R in multisession mode instead, then you can write more.

Better to do either of the above than to overburn, which may make CDs/DVDs unreadable on some systems. If your current writer goes bang, where is the guarantee that you will be able to read the disk in another drive?

There is nothing abt money or space.

This is all about utilizing knowledge and utilizing the resources at their best.
This is what I believe If you have something, use it at its best.

Rest different people have different ways to do different things. One may agree with you and one may not. But your or his/her work goes on.

I have tested this technique with Ubuntu Linux. It worked very smoothly in first go, fortunately. I used Moser Baer Pro Cd-R (700 MB capacity). I was able to write 978 MB data on this disc. It was readable in Linux on my pc later on, but not in windows. I am using Windows XP SP3.
