Why need to clone hard disk?

Through cloning/ copying a hard disk, you can make a duplicate of your current hard disk. It’s a nice choice to duplicate your hard drive under the two following conditions:

  • Upgrade to SSD or larger disk without apps and OS reinstallation: If you want to replace your old hard disk with SSD or a larger disk while keeping all apps & current OS, you can copy disk to transfer all data, including OS to another one.

  • Back up your system and data for safety: Through disk copy, you can get an exact backup of what stored on your hard disk in use. Thus you can quickly replace the original hard drive with the cloned one if the current disk is failing.

Without knowing the function of disk clone, I did suffer the tedious and tiresome work before. That happened when I just entered college and had my own PC. In order to avoid data loss due to my wrong operation since I was not familiar with using computer then, I decided to backup all the things on d disk to my USB flash drive. Then, I copied the files and folders one by one.

Though there were not too many matters on d disk for I had not used my PC for too long, it still took me almost a whole morning to finish the work. Besides, some files and applications copied by the "Copy" and "Paste" functions in right menu cannot be used. Had I know the service of disk clone then, I would not foolishly do the repeated work.

A step-by-step guide on how to clone hard disk

This guide will take cloning system hard disk to a smaller SSD as an example. To follow it, you can download AOMEI Partition Assistant Standard to have a try!

Step 1. Install and launch AOMEI Partition Assistant, and then click "All Tools" and "Disk Clone Wizard".

Tips: To clone only system drive to new disk, for example, move windows 10 to SSD , please select “Migrate OS to SSD” instead.

Step 2. In the pop-up window, choose "Clone Disk Quickly" as you are going to copy hard disk to a smaller SSD.

Note: AOMEI Partition Assistant provides you with two methods for cloning hard disk: "Clone Disk Quickly" which only copies the used space of the disk. "Sector-by-Sector Clone" which will copy all sectors of the disk no matter whether it is used or not.

Step 3. Choose the hard disk that you need to clone as the source disk and click "Next".

Step 4. Select the destination disk to put the data of source disk on, and then click "Next".

Tips: You can tick "Optimize the performance of SSD" to improve the reading and writing speed of SSD if the selected destination disk is a SSD storage. If there are partitions on the destination disk, they will be deleted. Therefore, if these data are useful for you, please make a backup of them with AOMEI Backupper.

Step 5. In this window, this program allows you to adjust the partition size on the destination disk.

Note: There are three options for you: “Clone without resizing partition”, “Fit partition to entire disk” and “Edit partition on this disk”. After finishing the adjustment, please click "Next". As you cloning to smaller SSD, the first option is grayed out.

Step 6. You can preview the disk cloning operating by viewing the "Pending Operations". To commit the "Pending Operations", please click "Apply" and "Proceed".

As for "Sector-by-Sector Clone", the detail steps are very similar to that of "Clone Disk Quickly". The only two parts that are different are step 2 and step 3. In step 2, you should select “Sector-by-Sector Clone” as the copy method; in step3, you should make sure that the size of the destination disk is no less than the size of the source disk according to the principle of the way of copy, no matter how less the used space is in the source disk. The rest operation is just the same as what described for "Clone Disk Quickly".


Tips:
●If the hard disk you want to clone contains system boot partition, the operation will be completed under the "PreOS Mode". Do not worry about that you don’t know how to get into PreOS Mode to operate, because Partition Assistant will help you; the only thing you have to do is to follow it.
To copy hard disk or migrate OS from GPT disk to MBR, the limitation of MBR partition style should be taken into consideration. MBR supports up to four primary partitions and no bigger than 2TB.
The deleted or lost files can only be copied to the destination hard disk through “Sector-by-Sector Clone” method.
In addition to hard disk clone, AOMEI Partition Assistant also provides "Partition Clone Wizard" for cloning a specific partition.
Dynamic disk, Offline disks could not be set as target disk.
