Need to extend C drive on Server 2012
C drive, also named as system drive, is an extremely important part on the (Server 2012) computer since the operating system is usually installed on this drive or partition. Besides the operating system, there are also many vital files, such as temporary files, browser caches, downloaded programs, applications, etc being saved on this partition.
As a result, C drive might be running out of space quickly and easily with time going by. Well, when your C drive is almost full and prompts the low disk space alert, what you can do to fix this problem? One of the best solutions is to extend system C drive by adding more free space to it from other volumes. For this task, there are two kinds of tools: Windows native Disk Management and third party partition manager.
Next, I'm glad to show you full solutions with 2 ways to help extend c drive on Server 2012. Select a corresponding tool and method based on your disk partition configuration.
Extend C drive with Server 2012 Disk Management
Disk Management is a built-in tool in Windows Server 2012 for users to manage their disk partitions in a graphical interface. They are safe and easy to use, but they only work under some restricted conditions. To extend the C drive via the “Extend Volume” will require you to delete the partition after the system drive.
Steps to expand C drive in Windows Server 2012:
Step 1. Open Disk Management: press Win+R to open Run program. In the Run dialog, type diskmgmt.msc and press Enter key.
Step 2. Right click the E drive (which locates after C drive) and select “Delete Volume” from the menu.
Step 3. After deleting E drive, it will turn into an unallocated space. Now, right click the C drive and select “Extend Volume”.
Step 4. In the Extend Volume Wizard, click "Next" to continue.
Step 5. Select the disk from which you need to take free space to C drive. And click “Finish”.
Disadvantages of disk management on Server 2012
Although Windows Server 2012 Disk management can shrink and extend volumes, both of them come with restrictions:
The “Shrink Volume” function can only make unallocated space on the right after shrinking a volume.
The “Extend Volume” feature only functions when the unallocated space is directly behind the target drive you need to extend.
In briefly, the “Extend Volume” option can only add the unallocated space to the left contiguous partition. Therefore, if you want to expand C drive in Server 2012, the only option is to delete the right adjacent volume. As shown above, to extend C drive, you have to delete E drive first. How tiresome! What's worse, it will lead to the disaster of data lose.
