Hi seti! Here's the best way to explain the difference between cloning and imaging!!
Cloning copies the complete contents of one drive—the files, the partition tables and the master boot record—to another: a simple, direct duplicate. Imaging copies all of that to a single, very large file on another drive. You can then restore the image back onto the existing drive or onto a new one.
Typically, people use these techniques to back up the drive, or when upgrading to a larger or faster drive. Both techniques will work for each of these chores. But imaging usually makes more sense for a backup, while cloning is the easiest choice for drive upgrades.
How much free space do you have on your Operating Drive??
Sorry if I'm asking dumb questions. I feel like I'm pretty much a expert with Macrium and I'm just trying to help!!
