    How much space is needed to make an image on an external hard drive


    This is probably a real basic question. I want to make an image of my hard drive using Macrium Free. The MBR is 100 MB and the primary drive is 471 GB. Do I need at least 471.1 GB of free space on the external drive for the image or does the imaging software compress the size so that a lesser amount of space is needed?

    It will apx. 60% of the SPACE USED, not the total size of the partition.

    i.e. If you USE 100 GB of the 471 GB, the image will be apx. 60 GB
