Necessity for deleting unallocated disk space in server
Unallocated disk space is a part of a disk which is empty but cannot be used by us. Since it is unavailable, many of us want to delete it. However, because it does not contain any data, it cannot be deleted directly. Luckily, there is a better way to deal with it. By signing a drive letter or allocating it to other volume(s), we can make use of it absolutely. But how? There are two choices.
Two choices for deleting unallocated space
To delete unallocated volume space making use of Disk Management
The first method is to take advantage of the self-contained function (disk management) in server. Click Start>>Control Panel, then double click Administrative Tools>>Computer Management. Of course, there are more ways to open Disk Management. At this moment, a window will pop out to confirm our authorization. Just click continue button to confirm it. Then, choose Disk Management to get the page which shows all the volumes the computer has, including the unallocated space.
By right-clicking the unallocated volume space, choosing New Simple Volume and following the wizard, we can sign a drive letter to the unallocated space. Or, we can right click the volume that is just on the left of the unallocated space, choose Extend Volume and following the wizard (take the default settings) to allocate the unallocated room to the volume. Both of the two ways will hide the unallocated disk space and in advance make use of it.
To delete unallocated partition space taking advantage of AOEMI Partition Assistant
The other choice is to take advantage of a kind of third party software. For example, AOMEI Partition Assistant Server is a good choice. Then, how to delete unallocated space with Partition Assistant? There are two solutions, by creating a new partition with the unallocated partition space or by merging the unallocated space to an already existing partition. However, no matter which one you choose, you have to download, launch and start Partition Assistant first. Quickly, the partition details will showing itself on the main interface similar to that of control panel but more intuitive.
Case1. Create a new partition with the unallocated space.
Step1. Right click the unallocated partition space and choose Create Partition.
Step2. In the pop-out window, you can specify the details of the new partition, including partition size (here surely you should choose the default size - the whole unallocated space), drive letter, file system, partition label and so on. You can still align the new partition by ticking “SSD partition alignment” after clicking “Advanced<<”. For selecting the number for partition alignment, if you know nothing about that, just leave it alone.
Step3. Click “OK” to have a preview of the new partition you are going to get. If it satisfies you, then just click “Apply” to start the operation. When it finishes, close it.
Case2. Merge the unallocated space to an already existing partition
Step1. Right click the unallocated part and choose Merge Partitions.
Step2. In the pop-out window, the unallocated space is automatically chosen. Therefore, you only have to choose the target partition to which you want to merge the unallocated space. Except the partition(s) behind/on the right of the unallocated part, other partitions are all under your choice.
Step3. Click “OK” to see the pending result. If there is nothing needing modification, click “Apply” to start merging. Close it when it finishes.
Both of the two methods will make the unallocated space been missing and make it be able to use.
Except the functions mentioned above, AOMEI Partition also have many other services, such as move partition, delete partition and copy partition. Now, AOMEI Partition Assistant has updated to version 6.3 and has being added many new features. Except standard and professional edition (for Windows 10/8/7), all the other editions support Windows Server 2003, 2008, 2012 R2. However, the standard edition is free of charge. General speaking, we should choose the right edition according to the OS (Operating System) we use and the problems we are going to solve.
