The benefits of cloning hard drive

Cloning hard drive is a way for migrating data on the hard drive to another hard drive. Users may clone hard drive to another hard drive with different reasons:

  • Cloning hard drive for securing data. There are so many accidents that will lead to data lose. If you have already duplicated the hard drive, no matter what accident happens, your data would be safe. Because once the data lose, you can take the cloned hard drive to replace the original one.

  • Cloning hard drive for replacing old hard drive. With the usage of your hard drive, you may feel that your hard drive is old, or the hard drive is not enough to store more data. Thus, you need to change your old hard drive to a new one, or to a bigger one.

  • Cloning hard drive for upgrading HDD to SSD. Computer users all know that SSD (solid state drive) has better properties than HDD (hard disk drive). So, more and more people would like to clone HDD to SSD for upgrading HDD to SSD to get a better performance.

What is the best disk cloning software?

There are many species of hard drive cloning software. But how to choose the best one? The best clone hard drive software should be powerful that can solve much problems for you. And AOMEI Partition Assistant is such a great powerful hard drive cloning software.

  • A good hard drive cloning software can clone hard drive from GPT to MBR disk and vise versa. AOMEI Partition Assistant allows you to clone GPT hard drive to MBR hard drive and vise versa. if the GPT has less than 3 primary partitions, AOMEI Partition Assistant will clone GPT hard drive to MBR hard drive directly without converting MBR disk to GPT. However, if the GPT hard drive has more than 3 primary partitions, the primary partitions beyond the third partition will be converted to logical partitions; meanwhile, if you are choosing sector-by-sector clone, this software will convert MBR to GPT disk first, and then, clone hard drive from one to another.

  • A good hard drive cloning software should support you clone hard drive from HDD to SSD. AOMEI Partition Assistant not only supports you clone HDD to SSD, but also supports you align SSD after clone.

  • A good disk cloning software should allow you to clone large hard drive to smaller one. AOMEI Partition Assistant allows you to clone large hard drive to smaller one as only as the cloned hard drive has enough space to stored the data on the old hard drive.

  • It also can be used to clone recovery partition. Recovery partition is important to computer users. If your system damaged, you can use the recovery partition to restore the damaged system in a few minutes. However, the recovery partition occupied a lot of space of local hard drive. But you can use AOMEI Partition Assistant to clone recovery partition to external hard drive and delete the original one to release a certain space of hard drive.

  • It should support large sector cloning. AOMEI Partition Assistant also allows you to clone a hard drive that is large sector.

For those features, the AOMEI Partition Assistant should be the best disk cloning software. Besides, it also has many other advanced features, like resize partition, format partition, create partition, etc.

How to clone hard drive with disk cloning software?

AOMEI Partition Assistant can help you clone hard drive from one to another easily and safely with a few mouse clicks. Here is the step-by-step guide of how to clone hard drive by using the hard drive cloning software AOMEI Partition Assistant.

Step1. Connect the destination hard drive to your computer first. Make sure it can be detected. Install and launch AOMEI Partition Assistant. Click Disk Copy Wizard at the left pane.

Step2. Then, you will get into Disk Copy Wizard, and here you need to select an appropriate method to copy disk. Here we highly recommend Copy Disk Quickly. Then, click Next.

Note: the sector by sector clone will clone every byte on the original hard drive no matter it is used or not. It will take more time and occupy more space, which is why we do not suggest you choose it.

Step3. Here, select the disk you want to copy. Click Next.

Select Source Disk

Step4. Choose a target disk to copy the source disk to (here you should choose the disk you connected to your computer before). click Next.

Select Destination Disk

Note: if the destination disk is an SSD, then, it is necessary to check the option “Optimize the performance of SSD”, so that the SSD will keep the best status after clone.

Step5. It will pop up a window to remind that all data on this selected destination disk will be wiped out after you save the operation to physical disk. Thus, you need to backup first if there is any important data on the destination disk. Here click Yes.


Step6. Then, you can edit partition size on the destination disk. Here we click Next directly.

Edit Partition Size

Step7. Then, you will get into the Finish page. Here will give you a note about how to boot from the cloned disk. Read it carefully, click Finish.

Step8. Finally, you will back to the main interface of this hard drive cloning software. Click Apply on the toolbar to submit all operations.



● AOMEI Partition Assistant will execute the task under PreOS mode.

● This disk cloning software allows you clone a specific partition. If the partition you are going to clone is system boot partition or has some applications running, the task will be cloned under PreOS mode.


With the disk cloning software AOMEI Partition Assistant, clone hard drive isn’t a complex thing. You only need a few simple clicks to do it. With this concise interface, even a non-technician can do it alone. Besides, it is a powerful partition manager so that if you do not satisfied the partitions on the destination hard drive, you can use AOMEI Partition Assistant to partition hard drive as you want. What’s more, if you are looking for free cloning software, the AOMEI Partition Assistant Standard is a great free hard drive cloning software, you can download it free to have a try.
