Although Partition Assistant is mainly designed for Windows hard drive partition, it comes with copy wizards – “Disk Clone Wizard” and “Partition Clone Wizard”. They help clone your entire hard disk/partition to another hard disk/partition for backup or data transfer. For example, when upgrading HDD to SSD, you can apply “Disk Clone Wizard” to transfer all data from the old HDD to the new SSD.

With this tool, you can copy hard disk to another place, which is helpful when you replace your current HDD or SSD with a new disk without reinstalling system. Take the following steps to proceed.

Note: The Standard Edition only supports MBR data disks clone, if you wish to clone MBR system disk, MBR to GPT, GPT to MBR, GPT to GPT, please upgrade to the Professional Edition.
