I want to "clone" by existing "C" drive to my "D" drive. Is this correct, source (old) hard disk would by Disk 1 (C drive), and destination (new) hard disk would be Disk 2 (D drive)? I want to keep all data untouched on my C drive. What bothers me, "Old Hard Disk Usage: if you plan to remove your old hard disk drive from your computer..." I want to keep and use my existing C drive, and have destination (new) as a (clone) backup in case of failure of my orginal disk C. Also, "Hard Disk Drives Structure," "Before cloning." and "After cloning" appears to make changes in my drive C. In, short, I need an exact copy of my disk C (operating system, boot etc).
