What does Partition Clone & Disk Clone Mean

Typically, one hard drive has many partitions, which show as C:, D:, among others.  Partition clone means to copy partition to another drive in a file level or sector level, like cloning your D: to E: or other partition. All content on the original partition will be migrated to the target partition. Make sure your target partition has enough space.

Disk Clone refers to cloning all partitions and files and other data in one hard disk to another hard disk, such as cloning HDD to SSD. Obviously, a disk clone will take more time to migrate your data. If you want to copy your hard disk to another, you need to do more preparations.

So, how do you execute the partition copy or partition clone? Is there any easy solution? Yes, we recommend you use the robust partition/disk cloning tool, EaseUS Partition Master, without data loss.
