cdrecord/brasero burn the ISO file as data file instead of as image

Following the wiki, I was able to burn a Cd witht he command:

$ sudo cdrecord -v driveropts=burnfree dev=/dev/cdrom -dao "isofile.iso"

Things seemed to go fine and I got this output:

But then when I mount the cdrom back, instead of the contents of the ISO image, I find the "isofile.iso" file!!
I tried installing brasero and using it instead, but the same thing happened, what could the problem be?

Re: cdrecord/brasero burn the ISO file as data file instead of as image

You should not be using the "-dao" switch and get rid of the burnfree thing as that is now deprecated and will be used anyways if your drive supports it, so:

sudo cdrecord -v dev=/dev/cdrom isofile.iso
