Hi all,
I have to create the Image of a CD containing the data as much as possible as it's actually stored on the cd.
How should I do?
It seems k3b can extract ISOs only, and a shell command I tryed (don't remember which) didn't work (data were still plain text, no bit-scrambling,eight-to-fourteen...).
Please help me.
PS: For those who want to know why I need it:
I don't want to duplicate protected CDs or anything. I'm just making an application to burn data on a cd in a specific way , and I have to verify how it is actually stored on it afterwards. The more the image is like the cd, the better.
well if it's data then an ISO is as close as you can get. you can create ISO's yourself just with a normal dd command "dd if=/dev/cdrom of=/home/user/mycdimage.iso"

My god. My respect for dd increases by the day. So by just doing a raw data dump, you have yourself an iso image! I would have thought it would be much more complex than that.
conventional data cdroms use iso9660 format, i.e. specification number 9660 as defined by ISO, the International Standards Organisation. an iso file is nothing more than a clone of that data format exactly, and for simplicitlies, and doses 8.3 formattings, sake, "iso9660" just turned into "iso" as a 3 digit extension.
To make an ISO image look similar to CD or DVD, I suggest using the option conv=notrunc when using dd. There are other forks of dd like dd_rescue and ddrescue which will do even better making the an image the same as a disc.
