Perhaps I'm not using the term "cloning" correctly.... I was under the impression that a CLONE was a bit for bit copy of the original drive to another drive. In my case, I'm just trying to copy the drive that came in a laptop (320G) to a 1Tb drive to put into the machine, and put the original in a static bag on a shelf to put back in if I'm ever to get rid of the laptop. And, the Windows7 backup and restore comes up with an error every time and will save nothing to the backup drive. So, it looks like I must first make an image of the original onto a third hard drive, then restore that image to the new 1Tb drive. Just another unnecessary step and time consumed that doesn't need to be consumed, plus a third hard drive. Then I'd imagine that the new 1Tb drive will have the same problem creating a backup and restore from Win7 that the original drive does, but then I always have the image (compressed), don't I?. The original Ghost copied bit by bit, and that was what I called a clone... not a copy or an image, and certainly not compressed! This is where errors creep into things. I want an EXACT copy, bit for bit, errors and all!! (If there are any!) That's the way it came to me, and that's how I want the new drive to be: an EXACT copy... a clone! If it isn't, it's not a clone, it's an image, and compressed at that! But you're right, it makes no difference what proprietary format is used, as long as you restore it with the same program you made the backup with. That wasn't my point. My point was that MOST cloning programs are NOT CLONING programs at all. They are proprietary data compressing copiers. You may call it a clone, but *I* won't, sorry! A "clone" by definition is an exact copy
