Unable to partition Unallocated space? This page introduces you how to fix the problem by converting MBR disk to GPT disk with EaseUS partition software.

Why am I unable to partition Unallocated space?

Recently, the hard drive on my dell computer stopped working and I bought a 4 TB hard drive to replace it. And at the same time I did a fresh install of Windows 10 on the new drive. It auto created two more volumes, both labeled as Unallocated. But the problem is that I can not create a partition on one of those random Unallocated volumes. I don’t know why it happened. Is there any efficient partition tool can help to partition Unallocated space?

Many users have encountered such a case when they tried to partition Unallocated space on a hard drive, but few of them can figure out the reason. Here we will give you the reasonable explanation. Actually the problem is that, your disk must be initialized as MBR disk, as we know MBR disk could only support 2TB storage disk, if you want to use the disk which is larger than 2TB, you must initialize it into GPT disk. That’s why you always fail to partition Unallocated space. After figuring out the reason, you might know clearly how to fix the problem. Obviously, you have to convert MBR disk to GPT disk. As long as you do it, you can successfully partition Unallocated space on your hard drive.
