Clone

A friend of mine bought a new disk. 250 gb sata2, but he already had exactly a disk like that. He is about to build a cabinet for the old disk and use the new one in his desktop. His problem was now that he wanted an exact copy of the existing disk. He asked me how to do it. I didn't come up with any good idea how to do it in windows. Mostly because i am becoming more and more unfamiliar with that OS. I told him to boot up a linux live-cd and run the command: `cat /dev/sda > /dev/sdb`. He was a little uncertain that it would work, so he asked me to come over and help him. So I did, while his fast disks cloned themselves we ate some cake. And only after a while he rang me and said that everything went very well booting the new disk. He was happy, and I got some cake..
