How to make iso image of optical drive in Ubuntu 12.04 linux that booted from live usb?
normal way as I understand is to use dd:
umount /dev/cdrom dd if=/dev/cdrom of=/media/EOS_DIGITAL/snow_leopard_cd_bydd
but /cdrom in live usb doesn't refer to optical drive , so is there a way to make iso image of cd drive using dd ? what should I put in dd then?
I have found that it mounted in on /dev/sr0
but will dd produce a proper iso image if I use /dev/sr0 instead of /dev/cdrom ??
Thank you in advance
