Extend Partition with Unallocated Space in Windows Server 2012 (R2)
When there is an unallocated disk space in Windows Server 2012 (R2), AOMEI Partition Assistant Server allows you to extend partition, create partition with unallocated space.
What is unallocated disk space?
As its name implies, unallocated disk space means the space that isn’t allocated to any partition; it is free logical space on the hard drive; it is unallowable to write any programs to this space. If you want to write applications for it, you have to extend a partition with the unallocated space or create a new partition based on this space.
Why extend partition with unallocated space?
When there is not enough space on a partition of a hard drive, many users would like to extend this partition with unallocated disk space. The reasons for increasing partition size with the unallocated space is concluded as follows:
• In order to improve the operating speed: As time goes by, the C drive is filled with files, which will affect the running speed of machine. At this point, it is necessary to extend partition C with unallocated space for higher running speed.
• In order to satisfy the demand for installing more applications: It is common that the hard drive is partitioned imperfectly at first and you may want to install more programs on the specified partition; but only to find that there is no enough space for you to do so. Therefore, you need to increase the size of that partition with unallocated space.
How to extend partition with unallocated space in Windows Server 2012?
Before figuring out how to extend partition with Windows Server 2012 unallocated disk space, you have to realize two cases of unallocated space position:
• Case 1: The unallocated disk space in Windows Server 2012 is right behind the partition that you want to extend.
• Case 2: The unallocated space is not right behind the partition that you plan to increase its size.
Increase partition size with unallocated space via Disk Management.
If you are in the first case, you can increase partition size with unallocated space via Disk Management through the following steps.
Step 1. Press Windows+R, enter “diskmgmt.msc” in the box and press Enter.
Step 2. Right-click the partition you want to extend (here is partition “E”) and choose “Extend Volume”. Then, click “Next”.
For case 1, the partition can be extended with the unallocated space easily via Disk Management. But if you are in case 2, the option of “Extend Volume” is grayed out. The partition can’t be extended via Disk Management.
Thus, you have to turn to third-party software to add unallocated space to the partition that you want to extend.
Notice: If you stick to extend partition with unallocated space via Disk Management, you have to delete the partition behind partition E to get contiguous unallocated space and the data on the partition will be lost.
