can i use raid even if i got a single hd and a non raid board?! i think i missed this thing. i knew that i could use raid on 2 separate disks of the same ammount and only if i had a raid compatible board (with hardware or software) but i didn't know that you could use it also on a single disk. > > so the only think to do is find a good backup utility that is able to > > make a copy of the entire system. if i copy the system by hand from a > > live-cd would that work? if so, what should i avoid to copy? > > > > You can just copy files from a live CD.
