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."

Unallocated space after disk cloning issue is common, for whatever disk cloning software you were using. So, the questions about the unwelcome unallocated space are coming to various computer forums. People feel uncertain about where it was brought and how to get rid of the empty space that seems to be quite useless.

First of all, the unallocated space is never useless, it's part of your hard disk and shall put into significant use. Next, the answer to why you got such space is merely because you applied the sector by sector clone function while cloning a hard disk or partition. 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.

How to Make Use of the Unallocated Space on SSD After Cloning

By simply converting the unallocated space to a storage drive partition can save you out of trouble, and make full use of every byte on your cloned hard disk. In fact, if you're the ones who're looking for a piece of easy-to-use software to clone system to HDD/SSD, or upgrade hard drive from the small to large or from the old to new, EaseUS Partition Master is an ideal choice! It supports to edit the unallocated space after clone by merging it to the neighboring partition directly.

Nevertheless, no matter how you cloned the drive in the previous step, as long as you are currently confronted with the unallocated space issue, you can still ask help from EaseUS Partition Master. First, download the free partition manager on your PC, and go through the following two options to deal with the current issue.

  • It won't hot image your drives or align them, but since it's coupled with a partition manager, it allows you do perform many tasks at once, instead of just cloning drives.
