What Does a Disk Clone Do?

Disk Clone, also known as hard drive cloning, is a process to make an exact copy of the source disk to the target disk, including operating system, partition layout, drive letter, system reserved partition/EFI partition (for GPT disk), recovery partition, customized settings, installed programs, personal data and so on. You can perform a disk clone whether it's a system disk or data disk.

In addition to disc clone, there are other two cloning methods:

  • System Clone: it can be used for Windows operating system migration. It moves only system partition where Windows is installed and all the boot related partitions, like system reserved partition, recovery partition, EFI system partition (if exists) to the target disk.
  • Partition/Volume Clone: it can help you with data migration. It will copy all the data from selected partition/volume to destination partition, which is also a way that can be used to clone dynamic disk.

Disk Clone vs System Clone: Which One You Need

Both Disk Clone and System Clone features can help you migrate operating system to HDD/SSD while ensuring a securely boot. They also help to avoid reinstalling Windows and applications when your computer fails to boot. But which one do you need to use in different scenarios? 

▶ Four Disk Clone Scenarios | Clone Entire Hard Drive 

1. Hard Disk Upgrade: Hard disk that comes along with your desktop or laptop will run out of its space sooner or later. At this time, you need to upgrade hard disk for big capacity by cloning smaller disk to larger disk.

2. Make a Duplicate Disk: If all the data on the current system disk are important, it is necessary to do a full backup of the source disk by cloning hard drive. Thus, you can copy your data back quickly in the event of a disaster. Also, if the original hard drive is damaged, you could replace it with the cloned hard drive to enjoy exactly the same configuration as before.

3. Data Migration: It can help to quickly transfer all the data on a disk to another, such as the Windows operating system, installed programs, system settings, personal files, videos, etc. Meanwhile, a copy of original hard drive can greatly avoid data losses due to computer failure.

4. Data Recovery: In order to avoid secondary damage to the hard disk during data recovery, it is necessary to clone the disk and then restore what you want from the cloned disk.

▶ Two System Clone Scenarios | Clone Only Operating System

1. Transfer OS only: Cloning only system partition is a quick way to migrate OS to new hard drive or SSD. Also, it's a great idea to enjoy both excellent performance and big capacity by using SSD for OS and HDD for storage.

2. Smaller Target Disk: Sometimes, users want to clone hard drive to smaller SSD to get better performance, but the cloning may fail if you use sector-by-sector clone to clone all sectors of a hard drive. At this time, it's a wise choice to clone OS only.

Powerful Hard Drive Clone Software for Windows PC

As one of the best disk cloning software for Windows 11/10/8.1/8/7/XP/Vista, AOMEI Backupper Professional owns the following remarkable features:

💾 Cloning Methods & Supported Disks
It provides three cloning methods accordingly: Disk Clone, System Clone, and Partition Clone, supporting all popular disk brands, such as Samsung SSDs, WD disks, Crucial SSDs, etc.
💻 Live Disk Cloning
It allows you to clone hard drive to another HDD or SSD without breaking off the running operating system (called "Live Disk Cloning" or "Hot Clone"). That is to say, it can run disk to disk clone while you are working on the computer.
🧿 Clone Used Sectors or All
By default, this disk clone software just clones the existing data (the used sectors) on the disk. If you would like to clone all the sectors on the source disk, whether it is used or not, please try the "Sector by sector clone" option.
🚀 SSD Alignment
If your target drive is an SSD, you could use "SSD Alignment" to accelerate the reading and writing speed of SSD. By the way, this feature can still extend SSDs' lifespan.

This hard drive cloning tool also helps you make bootable media when the Windows refuses to boot or you don't want to load operating system while cloning. Download AOMEI Backupper to have a try now!

How to Easily Clone a Hard Drive in Windows 11/10/8/7

AOMEI Backupper allows you to clone hard drive with different size in Windows 11/10/8/7/XP/Vista, including:

  • Clone hard drive to larger drive (eg: clone NVMe SSD to larger NVMe) to get more storage space and better performance.

  • Clone larger disk to smaller disk, like cloning larger HDD to smaller SSD, cloning larger SSD to smaller one, etc. 

But there is a precondition. That is the space on the destination disk is able to accommodate all the valid data on the source disk. If there is not enough space on the destination disk, AOMEI Backupper will calculate and inform you that: The selected disk is too small, required the disk size at least: ** GB when you select the disk as the destination.

Then, let's see the detailed steps to clone disk as follows (take cloning hard drive to SSD as an example).

◑ Before Cloning

  • Please note all data on the destination disk will be overwritten after cloning, so backup important files ahead of time.
  • If you want to clone hard drive to external drive, please connect it to your PC beforehand. If it's not initialized, please initialize it in Disk Management before cloning.

◑ Steps to Clone HDD to SSD

This graphic guide will show more details about how to perform disk to disk clone. You could follow it to have a try:

Step 1. To clone a hard drive, select "Disk Clone" option under the "Clone" tab.

Disk Clone

Step 2. Select the source disk (Disk0) which you want to clone, and then click "Next".

Source Disk

Step 3. Select the SSD as destination disk (Disk1) to store all cloned data, and then click "Next". 

Destination Disk

If the destination disk is not empty, you will be prompted the destination disk will be overwritten or deleted. Click "OK" to continue as you have made a backup before.

Backup Data First

Step 4. As you are cloning hard drive to SSD, it is recommended to check the box before "SSD Alignment" to optimize the performance and lifespan for SSD. Confirm the settings, and then click "Start Clone" to clone HDD to SSD safely.

Helpful tips
✍ "Sector by sector clone": clone all sectors on source disk to destination disk, no matter they are used or not. If you clone large hard drive to smaller SSD, DO NOT choose this option, or the cloning process will fail.
✍ "Edit Partitions": make the target drive show full capacity when cloning disk to a larger one. The option "Add unused space to all partitions" and "Manually adjust partition size" are available.

Step 5. Click "Finish" when all the disk cloning operations have been done.

  • In general, the disk that contains the current operating system cannot be used as the destination disk. To complete that for special purpose, you can create a bootable disc and perform cloning in WinPE mode.
  • If the destination disk is a dynamic disk, you have to convert it to basic disk without losing data first. Or you can turn to "System Clone"  and "Partition Clone" feature for help.
  • To clone disks on any computer anywhere and anytime, you may use AOMEI Backupper Technician or Technician Plus to create portable version

This is a quick navigation to the entire process of hard drive clone. Compared with the graphic guide, it is more intuitive and easy to understand. You can check it before cloning.

◑ Boot from Cloned SSD

If you're cloning the disk with operating system installed, it is suggested to restart your computer and continuously press a specific key (usually F2, F8, F12, Del) to enter BIOS Setup -> Boot, then set the cloned disk as first boot device in BIOS or replace the old hard drive with the new drive directly to boot from the cloned drive.

FQAs about disk cloning

1. Does Windows 10 have cloning software?

No, Windows 10 does not have cloning software. There is a built-in tool called Create a system image. However, it only works if you are transferring system image to a larger hard drive.

2. What is Disk2Disk?

In fact, disk clone is also called "Disk to Disk (Disk2Disk)". There is a similar function - disk imaging, which can store all the data on a disk to an image file. That is the so-called "Disk to Image (Disk2Image)". AOMEI Backupper can realize Disk2Disk as well as Disk2Image. It can backup your disk to an image file so that you can restore your disk in the future.

3. How long does it take to clone a hard drive?

The time it takes to clone a hard drive depends on several factors, including the drive size, cloning method, and the speed of your hardware. Generally, the average wait time would be between 10 mins and 1 hour.

4. Can I clone a 1TB HDD to a 512GB SSD?

Yes, you can clone a larger HDD to a smaller SSD as long as the used space on the HDD doesn’t exceed the SSD’s capacity.
