Why need to 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 some applications cannot be pasted and keep bootable 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. Partition copying offers several advantages, making it a valuable tool for both personal and professional use. Here are some of the key benefits:

1. Data Security and Backup: By copying a partition, you create a replica of your data, ensuring you have a complete backup. This can protect against data loss due to hardware failure, malware, or accidental deletion.

2. Efficient Disk Management: Partition copying can be used to reorganize disk space. For instance, you can move a partition to a new drive to free up space on the original disk or to optimize performance by placing frequently accessed data on faster drives.

3. Consistency Across Multiple Systems: For businesses or IT administrators, copying partitions allows for the deployment of identical system configurations across multiple machines. This ensures consistency, simplifies maintenance, and speeds up the setup process.

Two partition copy methods from free AOMEI Partition Assistant

When the Microsoft does not provide partition clone service. It is necessary to turn to some professional partition copy software like: AOMEI Partition Assistant Standard. It can satisfy all mentioned needs including copy recovery partition and hidden partitions without losing data. 

AOMEI Partition Assistant Standard provides Windows PC users with 2 different copy methods: " 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, whether 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.

Step-by-step guide: How to copy a partition to another hard drive

💡 Notes:
  • The target drive must have an unallocated space. 

  • The unallocated space must be equal or larger than the used space on the source partition according to method 1. Based on method 2, the unallocated space must be equal or larger than the 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 a 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).
