Why do you need portable disk cloning software?

Owing to complex steps and a low success rate, many people won’t choose Windows features to transfer the data from one disk to another. They intend to utilize third-party software to clone important data or migrate HDD to SSD because of the easy operation and a better chance of going ahead.

If you need to clone one hard disk to more than one computer, you will have to install that software on each one, and don’t forget about the license issue.

Thus, portable disk cloning software is the best solution to clone and manage multiple devices without too many limits.

How to Clone hard drive with disk cloning software

After you’ve created a portable version of Partition Assistant, now, let’s see how to clone a hard disk to a smaller SSD as an example. Your apps are safe and you don’t need OS reinstallation if you want to directly replace your old hard disk with the new one.

Before the cloning, please connect the removable device installed in the portable version of AOMEI Partition Assistant to the computer with the disk you wish to clone. And launch the software from the device.

Step 1. Right-click the disk you want to clone in the main window and choose “Clone Disk”.

Clone Disk

Tip: If you just want to clone OS only, you can choose the “Migrate OS to SSD” feature in the left menu.

Step 2. In the pop-up window, choose "Clone Disk Quickly" as you are going to copy the hard disk to a smaller SSD. “Sector-by-Sector Clone" will copy all sectors of the disk no matter whether it is used or not, so you should make sure that the size of the destination disk is no less than the size of the source disk in this situation.

Step 3. Choose the target disk to place the data of the source disk, and then click "Next".

Destination Disk

Note: You can tick "Optimize the performance of SSD" to improve the reading and writing speed of SSD if the selected destination disk is an SSD storage. If there are partitions on the destination disk, they will be deleted.

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

Edit Disk

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

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


If the hard disk you want to clone contains a system boot partition, the operation will be completed under the "PreOS Mode", so don’t worry, just follow the steps.

To sum up

To realize a hard disk clone among multiple devices simply, AOMEI Partition Assistant will be the best portable disk cloning software for you. The software also has other pragmatic features not only cloning: move applications, make bootable media, resizing BitLocker partition… With this handy tool, cloning disks on different PCs will be easy for everyone.
