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

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? no mkisofs?

you should checksum your images anyway, will not `dd` be marginally faster?

dd bs=2048 if=/dev/cdrom | tee image.iso | md5sum | tee image.iso.md5

Sure, you can checksum, and if it doesn't match up, you get to do it again? Why not fix the errors on the fly? And no, dd won't be marginally faster. It will move at the same pace as readom- the pace of your hardware.
