Actually it makes perfect sense if you think about it, consider this: A Compact Disc consists of the Plastic Plater with pits in it and a reflective metal (simply put that is) now consider each pit a 0 and each non-pit a 1, dd should be able to read the pits and non-pits as a binary stream and save it to disk as an image (call it .img or .iso it makes no difference) now concerning HFS, Juliet, or RockRidge or what it is, it just like the difference between a elf and MS-DOS executable, both are binary files made up of zeros and ones but it is how the zeros and ones are arranged that make them different. > > These questions just popped up.
