As a safeguard to a bootable hard drive failure, can you make a exact clone of a good hard drive install including OS, programs, files, prefs, etc on a dvd rather than on another hard drive? I'd like to have a good "clean" copy of my OS, programs, files etc stored away so that if my bootable main drive goes out, I can simply copy over the cloned dvd - Operating system and all - onto a new hard drive and be up and running in minutes rather than hours or days. Is this possible on a dvd? If so....how does one accomplish that and how do you recover the OS and all the other contents of the dvd back onto a fresh hard drive that will then boot right back into windows ? Thanks.
