Acronis’ Live Chat Line claims it is not possible “because having two bootable hard drives on the same machine would cause a conflict”; further, that I would need to unplug this second drive from the machine – yuck. With due respect, I believe this is incorrect because my second drive is not listed in my BIOS boot sequence of where to sequentially look for an OS. I’m interested in this as a learning exercise, as I am also learning how to deal with hardware inside the machine; it would give me great peace of mind to know that if my C drive crashes… that I truly have another drive ready and able. (Yes, I know that an image of C on a backup drive could be restored via a bootable CD onto a new drive in the C location – I’ve already prepared for that. As I said, for me this is a learning exercise.) I would like to do a dry run placing a clone of C: on my second hard drive (plenty of capacity) and then swap the second drive to function as C: (swap master/slave jumpers, etc). In either case (clone or image, per the above), my preference for this type of system backup would be a once-in-a-blue-moon event (after important software changes, when the machine is working OK, etc) because I regularly back up my data by other means. Comments anyone? – Thanks!
