Solution to increase partition size in Windows 2008 Server

All the size of the hard disk partitions are carefully allocated while building the 2008 Server. However, things are changing and the scheduled size may not always meet your needs, especially for the system C: drive, you’ll be amazed how quickly applications, Windows updates install, browser caches, and temporary files eating up your free space and clutter your system. In this situation, you can extend C: drive with free space in other volumes of the same disk. Forget the old stupid method to back up and start over. By resizing partitions, you can solve this problem within half an hour to several minutes if you use the right tool. In this article, I’ll show you how to increase partition size on Windows Server 2008 (R2) without losing data, fast and easily.

Which tool to increase Server 2008 partition size?

Generally speaking, there are two kinds of tools: Windows built-in Disk Management and 3rd-party partition software.

1. Disk Management snap-in

Better than previous Windows Server 2003, Server 2008 Disk Management console provide new function to resize disk partition. Shrink Volume is used to reduce partition size, and Extend Volume is used to increase partition size. However, due to the limitations, it is not the best tool to resize partition, I’ll tell you why in next paragraph.

2. 3rd-party partition software

The task to resize partition and increase C drive space becomes much easier if you use 3rd party software, here I recommend NIUBI Partition Editor, which is compatible with Windows Server 2016/2012/2008/2003 and Windows 10/8/7/Vista/XP (32 and 64 bit). All types of hard disk drive, USB disk, memory cards, VMware/Hyper-V and all kinds of hardware RAID are supported.

Main benefits:

  1. All-in-one solution – besides resizing partition, it has many functions to manage disk partition and improve server performance.
  2. Unique Roll-Back Protection technology to keep OS and data intact, even if power failure or other hardware issue occurred during resizing partition.
  3. Hot Resize technology to extend NTFS partition without rebooting.
  4. Preview all partitioning operations before executing.

How to increase partition size?

Some people like to use Windows built-in utility, so I’ll introduce the steps with DM first.

Increase partition size in Server 2008 Disk Management

Note: only when there is adjacent Unallocated space at the right side, you can expand a volume, otherwise, ignore this method.

Step 1: Right-click the partition you want to expand and select “Extend Volume…”

 Increase partition sizeStep 2: In the pop-up window, select the available disk and free space, click Next.

Add space

Step 3: Confirm the operation and click “Finish” to proceed.

Confirm extending

However, not every drive can be extended. When right click C drive, the Extend Volume is greyed out. From Microsoft explanation, only when there is adjacent Unallocated space behind, you can expand this NTFS partition. This is the reason why I said Disk Management is not the best tool to resize disk partitions.

To decrease and increase partition size on Windows Server 2008, I always recommend NIUBI Partition Editor. Besides the unique Roll-Back data protection technology, its unique file-moving algorithm helps resize partition 30% -300 faster than other tools, which is strictly tested. In some situation such as large amount of files in the volume you want to resize, high CPU usage rate and low server memory, this software can be 500% faster.
