Need to clone my Samsung external hard drive

“As my 500 GB Samsung external hard drive contains plenty of files and is with many programs installed. To avoid data loss when my external hard drive is corrupted, I want to clone it to another 1 TB external hard drive in Windows 10 for a backup. So how can I copy the external hard drive to another one? Is there any advice or information? Thanks a lot!”

Advanced software for (external) hard drive clone in Windows PC

It’s not a bad decision to duplicate an external hard drive or internal hard drive for protecting important data stored on it. But how can you do that? In fact, it will be an easy task as long as you find out right hard drive cloning software. Among a lot of cloning software, AOMEI Partition Assistant Professional is highly recommended for Windows 11/10/8/7 and Windows XP/Vista users.

This advanced hard drive clone software offers two copy methods: “Clone Disk Quickly” and “Sector-by-Sector Clone”. The first one only copies used sectors or all sectors on the source external hard drive so that the destination disk can be smaller than the source disk as long as it has enough space to hold the used space of the original disk. The second method will clone every sector to the destination disk no matter it is used or not. If there are bad sectors on the source external hard drive, this method is useful.

In addition, this cloning software supports copying system disk to another disk and boot from the destination hard drive after clone so that you can upgrade or replace the current boot disk without reinstalling Windows and other pre-installed software.
