I currently run XP with 1 SATA drive. I'm about to install a new MB and SATA HDD. Can I partition the new HDD which is 1 terabyte in half and "mirror" 1 side of it with my current HDD which is 500 Gbyte (w/ currently 83% free space) so I have a backup of it while installing WIN 10 on the other partition of the 1 terabyte and have selection to either OS?
