About Partition

If we compare a hard disk as a bookrack, a partition is a shelf in the bookrack. Only the hard disk is repartitioned as partitions such as C:, D:, E: we usually see in "My Computer", data can be allowed to store on it. A hard disk can be divided into several partitions, and usually there are three or four partitions on a hard disk to store data separately.

Why Need to Clone Partition in Windows 10?

It is clear from what mentioned above, all of the data are stored on partitions. With time goes by your present hard disk may be damaged by hardware failure or wear out. So the data stored on partition are in the risk of being lost. What’s more, for some users of Window 10, in order to manage data easily they have the habit of storing their essential data on the same partition. To protect data for these users, there is no need to clone the whole disk, just clone partition is enough.

Although to make a duplicate of your important data, you can copy and paste them one by one into another space, but you can’t copy and paste the running programs. Besides, it is a time consuming work, if there are large amount of data.
