I have 80 GB Pata HDD and it's getting low on space.I am thinking of adding another 500GB SATA. What I want to do is make the new 500 GB HDD primary and old one secondary for backups. And also make it my OS HDD. How can i transfer all my OS and files to the new HDD. IS it possible to do by Clone software, if yes by which and how. Please advise.
