Why need perform "partition copy" ?

"I’d like to transfer all content on my partition D: to another drive. I know the manual copy and paste does not work in this situation since there are some applications that cannot be pasted and keep bootable afterwards. So i need to clone the whole partition. However, the Microsoft Operating System does not offer such tools for partition copy. Is there any magic software for me?"

Partition copy means cloning one partition to another. All content on the original partition will be migrated to the target partition. When the Microsoft does not provide partition clone service. It is necessary to turn to some professional partition copy softare like: AOMEI Partition Assistant Standard. It can satisfy all mentioned needs including copy recovery partition and hidden partitions without losing data. At the same time, it provides two types of duplication which will be introduced below.

Two partition copy methods from free AOMEI Partition Assistant

The AOMEI Partition Assistant Standard provides Windows PC users with 2 different copy methods; they are ”Clone Partition Quickly“ and "Sector-by-Sector Clone". What makes them different and which one you should choose?

1. Clone Partition Quickly: it is also called file-by-file copy. Only the used space can be copied to the destination location and it is recommended because of its fast speed. During the duplicated process, you can resize and move the partition at the same time.

2. Sector-by-Sector Clone: All sections, no matter whether it is used or not, in the source partition will be cloned to the target partition. Compared with the first one, it is available to clone deleted or lost files and inaccessible data to target drive. In addition, it supports only the function of moving drive, meaning you cannot resize or edit any partition during that process.

Partition copy to another drive step by step

The target drive must have an unallocated space. 
The unallocated space must be equal or larger than the used space on source partition according to method 1. Based on method 2, the unallocated space must be equal or larger than original drive.
If the target partition is on an MBR disk, then no matter how large your free space is, it is unavailable to build a target drive if the number of primary partitions is more than four, including four. But if there are three, the destination drive you create only can be logical partition.

The following example will show how to clone  partiton to another hard drive with method 1 (This is only applied to clone MBR data disks to MBR disks).
