Move and merge Unallocated space on Windows Server 2016
Windows Server 2016 provides built-in Disk Management utility, but it cannot move Unallocated space or disk partition. Extend Volume functionality can only merge Unallocated space that is adjacent and on the right side.
In this article, I’ll show you how to transfer/move Unallocated space on Windows Server 2016, and how to combine/merge Unallocated space by 1 step to drag and drop on the disk map.
Be caution when moving Unallocated space
Windows Server 2016 Disk Management cannot move Unallocated space, so you need third party disk partition software. Partition software is much more powerful, but it may cause system and/or data damage. When moving Unallocated space, the parameters of disk, related partition should be modified correctly, in addition, all files in the related partition should be moved and updated, too. Any slight error will cause damage. Thus, you’d better back up and select the safe tool.
Among the server partition software, NIUBI Partition Editor is recommended as the safest and fastest. If any software error or hardware issue occur while moving partition and Unallocated space, it is able to revert the server to original status automatically and rapidly. Thanks to its unique file-moving algorithm, it is 30% to 300% faster than other tools.
To move and merge Unallocated space on Windows Server 2016, you just need to drag and drop on the disk map.
How to move Unallocated space to C drive
When system C: drive is running out of space, many people try to extend it with Extend Volume in Disk Management. However, Extend Volume is disabled for C drive after shrinking D, because the Unallocated space is nonadjacent to C drive. In this situation, you just need to transfer Unallocated space from right of D to the left side, then Extend Volume is enabled.
How to move Unallocated space in Server 2016 with NIUBI:Download NIUBI Partition Editor, right click drive D and select Resize/Move Volume.
Drag the middle position towards the right side in the pop-up window.
Click OK, Unallocated space is moved to the left side. Click “Apply” on top left to execute.
How to merge Unallocated space?
When there is adjacent Unallocated space on either side, you just need 1 step to drag and drop with NIUBI. After the step above, Unallocated space is moved to behind C drive.
How to merge Unallocated space to C drive in Server 2016:
Right click C drive and select “Resize/Move Volume” again. Drag the right border rightwards in the pop-up window.
Unallocated space is combined to C drive.
Move/merge Unallocated space to other drives
If you do not want to move and merge Unallocated space to C drive, you can combine or move it to right side of drive E, or to the end of disk step by step.
Combine Unallocated to partition E
Extend Volume only works when the Unallocated space is adjacent and on the right side, so you cannot extend drive E after shrinking D in Disk Management.
If you want to combine Unallocated space to drive E, similarly, right click E and select “Resize/Move Volume”, drag the left border leftwards in the pop-up window.
Move Unallocated space to right of E
If you do not want to extend partition E, you can move Unallocated space to the right side of E, and then combine to partition F.
Right click E and select “Resize/Move Volume”, drag the middle position leftwards in the pop-up window.
If you want, you can also move Unallocated space to the end of disk.
Windows Server 2016 Disk Management is unable to move Unallocated space, furthermore, Unallocated can only be combined to left adjacent partition. To move and merge Unallocated space in Server 2016, NIUBI Partition Editor is the best choice because of its powerful data protection and fast moving ability. To merge Unallocated space to C drive or any adjacent partition, drag the border towards other side, to move Unallocated space, drag the middle position towards the other side.
