Copy CD/DVD to .iso

Installing from physical CD’s or DVD’s is always a hassle, first actually putting your hands on the disc you want can be quite a process. On and around my desk sit a number of 100 disk spindles, digging through them is always a hassle. Disk space is cheap, and the time saved by mounting an .iso can go a long way to paying for the disks. Not to mention physical optical disc’s are SLOW! I keep a mount point reserved on my filer to store everything I use frequently as .iso’s. Now when I need to spin up a Virtual Machine (VM) or even install to bare metal I simply mount the .iso and away we go, but at gigabit speeds instead of waiting for the slow transfer speeds of optical drives.

With Linux, it’s a simple as finding the disc and using the dd command.

dd if=/dev/sr0 of=/path_to_store/discname.iso

That’s all there is to it. You may have to adjust the input device name to suit your particular setup, typically something along the lines of /dev/sr0, /dev/cdrom, /dev/dvd etc..

From here, lather, rinse, repeat. Then store your optical discs in a safe place, or use them for coasters. So long as your storage media is intact you will generally not need them.
