Why clone partition in Windows 10?

Cloning partition can be also called copying partition, which is a process of moving whole partition data into another new partition or hard disk. There are many reasons why you might want to make a copy of a partition in Windows 10/8/7.

The first and foremost one is to make a backup so that you can quickly get back important data when your hard drive fails. The second one might be transferring a large amount of data more conveniently and safely. For example, when you want to move everything including installation packs from one partition to another hard disk volume, SSD, HDD or other hard drives, it’s better to clone partition than copying files one by one which may cause programs or OS failure.

Free software to clone partition in Windows 10/8/7

Now, you might wonder "can Windows 10 clone partition". Sorry to tell, “NO”. Microsoft has not ever provided such a cloning tool in Windows. Although you can copy files from one drive to another by dragging and dropping, it is not advised especially when it contains some boot files.

Therefore, in order to make a complete clone of the original partition, which contains some hidden stuff such as partition table, you need to use specialist partition clone software. Here we bring the free software: AOMEI Partition Assistant Standard. It allows you to duplicate partitions or volumes in 32-bit and 64-bit of Windows 10/8/7 for free. Moreover, this software provides the following two different partition cloning methods to meet different demands:

Clone Partition Quickly: copy all existing files from one partition to another partition or hard disk. In this method, the total space of destination location should be large enough to hold all existing files on the original partition.
Sector-by-Sector Clone: copy all available files and lost/deleted files from the source partition to destination space. So the target disk space should surpass the total space of the source partition.
