Overburn a CD

My friend once brought a CD and made an image on my system. He wanted
me to make a copy of it. When I burnt the CD for him and checked it
later, I found that the CD had a total of 1.27 GB of data on it. How
is this possible on a 700MB capacity CD? And I could see on the CD
that there was space left for at least another 50-80MB of data. Could
some please explain this to me.

first of all, you can't overburn a CD to double it's capacity, you can
a few MB more but not to that extreme. some software, however, will
repackage the software when you create the iso and will create one
copy of each file and if it appears twice it will only create a
shortcut to the file.

that is the case when you create the installation CD for win2k
pro,srv,adsrv

so what you end up is about 600MB of files with some shortcuts in some
other directories to the same files, which makes it look like the file
is written again.

one utility that will do this is cdimage.exe you can find it at

Hey Lehi,
Thanks for all the help on that one. Could you please also tell me
whether there is any way that we can find out as to what is the limit
that we can overburn a CD. I have tried it a couple of times, but I am
also afraid that I might overdo it. And also, do let me know if there
are any disadvantages to overburning a CD.
Regards,
-Jason.

i've read that you can damage your burner, but to be honest i've never
done it, cds being so cheap i rather buy more cds than having to buy a
burner. perhaps someone else has the answer. anyone?
