About the Unallocated Space After Cloning

"I see unallocated space after cloning a smaller HDD to a larger one. What's the matter? I feel so sure that there is no such unallocated space on the source disk. By the way, it's EaseUS disk clone software that I use."

First of all, the unallocated space is never useless, it's part of your hard disk and shall put into significant use.

For example, EaseUS Todo Backup disk clone feature allows you to clone system files and partition tables sector by sector, byte by byte including the bad sectors if there were some. That's how you ended up with an exact copy of the original drive but meanwhile obtain some unallocated space.
