Then, how to clone the disk with AOMEI Partition Assistant? Please follow the text below.

First, you need to install the second hard drive to the PC. If your computer has only one hard drive slot, then you will need a USB adapter to connect the disk to the computer.
If the disk is brand new, you need to initialize the disk, set the partition style of the new hard disk needs to be the same as the old hard disk. If not, please convert it from MBR to GPT or GPT to MBR.

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

✍Tip: 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. 

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

Edit Disk

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 clone to a smaller SSD, the first option is grayed out.
