Create a CD/DVD ISO image from disk.

Many like to use 'dd' for creating CD/DVD iso images. This is bad. Very bad. The reason this is, is 'dd' doesn't have any built-in error checking. So, you don't know if you got all the bits or not. As such, it is not the right tool for the job. Instead, 'reaom' (read optical media) from the wodim package is what you should be using. It has built-in error checking. Similarly, if you want to burn your newly creating ISO, stay away from 'dd', and use: wodim -v -eject /path/to/image.iso
This is sample output - yours may be different.

How to copy CD/DVD into hard disk (.iso)

A dear friend of mine asked me how do I copy a DVD to your hard drive? If you want to make a copy of the ISO image that was burned to a CD or DVD, insert that medium into your CD/DVD drive and (assuming /dev/cdrom is associated with your computer?s CD drive) type the following command

What Others Think

But... You don't have to remember the dd syntax. Under Unix, everything's a file, so these will work too: cp /dev/cdrom ~/cdrom_image.iso cat /dev/cdrom > ~/cdrom_image.iso

@flatcap: That's good to know, thanks. I'm an Ubuntu user by default, lol.

o0110o · 647 weeks ago

Wow, thats very good to know, flatcap. But does that mean you can do the opposite: cp ~/cdrom_image.iso > /dev/cdrom To write an ISO to a disk? I don't think it does, but why wouldn't that work then?

@o0110o: I should have been clearer. My two commands will work under all Unix-like OSs (Ubuntu included).

flatcap · 646 weeks and 6 days ago

@raikia: Hmm... Now you've got me. I don't know. I think not. cdroms are awkward things. It'll certainly work with most normal block devices. I sometime use that method for disks, e.g. cp /dev/sda1 2012_07_10_sda1.img cat 2012_07_10_sda1.img > /dev/sda1

The only problem here is that there is no error checking or correction. The cdrecord package includes a command line tool called readcd that rips CDs to iso files quite nicely: readcd dev=<cdrom> f=foo.iso
