Running WinXP and have a custom two hard drive pc. One hard drive is 20gb, the other 160gb. I'm fixing to change the 20gb drive to an 80gb drive. Using Acronis cloning feature: 1. Any problem cloning from a smaller to a bigger drive? 2. Any problem cloning from a bigger to a smaller drive, given the total smaller disk capacity is adequate? 3. I have drive C and drive D. Does the cloning redesignate or flip-flop drive designations? 4. Does the cloning process erase the destination disk ahead of the clone image being written to it? 5. Once I have a primary and clone image/drive in place, does the clone drive/image stay static, or do both change together as something is written to one or the other? 6. By using the clone as a backup approach, would it be beneficial to use a boot loader program?
