Server 2008 Shrink Extend Partition

How to shrink and extend volume on Windows Server 2008?

All the sizes of physical disk partitions or RAID array virtual drives are allocated while building the Windows 2008 Server, however, the scheduled size may not always meet your needs, for example:

  1. System partition was created too small and no free space left after a long time.
  2. To manage files more effectively, you need to shrink the large partition and create more smaller ones for different usage.
  3. A data partition is too small, but files keep going into it.

Comparing to the previous Server Operating Systems, Windows Server 2008 Disk Management console provides new feature – “Shrink Volume” and “Extend Volume”, which can be used to decrease and increase partition size. However, you cannot extend the system C drive by shrinking other data drive in this console. In this article, I’ll show you how to shrink volume and extend volume on Windows Server 2008 (R2).

Shrink Ability Comparison

Compare with Disk Management and 3rd-party software

  1. When you shrink a partition, unmovable files (for example, the paging file or the shadow copy storage area) are not automatically relocated and you cannot decrease the allocated space beyond the point where the unmovable files are located. In this case, you can only shrink a little space.
  2. When you shrink a partition, the Unallocated space can only be created behind it.
  3. The Unallocated space shrank from a partition can only be used to create new partitions.
  1. You can shrink volume to any size, because it is able to move files.
  2. You may drag either left or right border of this partition to shrink, so the Unallocated space can be created before or behind this partition.
  3. Besides creating new partitions, the Unallocated space can be used to extend any drive in the same disk.

Compare with disk management and 3rd-party software

  • Server 2008 Disk Management can only extend a volume when there is adjacent Unallocated at the right side.
  • 3rd-party software has the ability to move the Unallocated space, so it is able to extend C drive by shrinking any other data drives.
