Resize/Extend hard drive partition on Windows Server 2008

It is not an easy task for many server administrators to resize hard drive partition without losing data. This article shows how to shrink and extend hard drive partition on Windows Server 2008 (R2) with native Disk Management and safe disk partition software.

Resize hard drive with Disk Management

In previous server 2003, Microsoft provides diskpart command prompt to manage disk partitions. It is able to shrink and extend part of the hard drive partitions, but it is not easy to use. In addition, Unallocated space won’t be shown in diskpart command prompt. To make it easier to use and enhance the ability, Microsoft adds GUI Disk Management utility to Server 2008.

However, the same with diskpart command, Server 2008 Disk Management has limitations when resizing hard drive partitions.

  • Both Shrink and Extend Volume functionalities support NTFS partition only.
  • Sometimes you can’t shrink C drive with Shrink Volume even though there is free space in it.
  • Shrink Volume can only shrink a volume towards left and produce Unallocated space on the right side.
  • Extend Volume can only extend the hard drive with adjacent Unallocated space. Furthermore, Unallocated space must be on the right side.

The most common issue is that you can’t extend C drive by shrinking D in Disk Management.

As you see in my test server, Extend Volume is disabled for C drive after shrinking D, because the Unallocated space is nonadjacent to it. Extend Volume is greyed out for drive E, because Unallocated is on its left side.

Extend Volume disabled

Windows native Disk Management has part of ability to shrink and extend partition, but because of these limitations, it is not the best tool to resize hard drive partition on Windows Server 2008 (R2).

If there is plenty of free space in any drive of the same disk, simply shrink it and transfer free space to the hard drive that you want to extend.

If there is no other drive or not plenty of free space in all other partitions, clone disk to a larger one and then extend hard drive with extra space.

To extend hard drive partition on Windows Server 2008, native Disk Management can do little help. You need other partition tool, but because of system and data safety, you’d better back up first and run reliable program.
