Add space to C

Move and add Unallocated space into C drive

This article introduces how to add Unallocated space to system C: drive on Windows Server 2008 (R2). Move and combine Unallocated space into C drive by drag and drop.

Cannot shrink D to expand C

Microsoft improved the ability of native Disk Management by adding new Shrink and Extend Volume functionalities, so many server administrators try to repartition hard drive when system C drive is getting full. Actually, Disk Management still cannot extend C drive by shrinking D or any other partitions. The key limitation is that Extend Volume only works for the partitions with adjacent Unallocated space on the right side.

Shrink Volume can only shrink D drive towards left and produce Unallocated space on its right side, but to expand C drive with Extend Volume, Unallocated space must be on the right side of C. So you can’t add Unallocated space to C drive except you can move Unallocated space to the other side.

Server 2008 Disk Management cannot produce or move Unallocated space to the left side of a volume, so to accomplish these tasks, you need 3rd party partition tool.

How to move Unallocated space

Caution There is potential system and data damage risk when resizing disk partition, so remember to back up and run reliable partitioning software,

As the safest partition manager software, NIUBI Partition Editor provides 1 Second Rollback, Virtual Mode, Cancel-at-will technologies to ensure system and data intact. In addition, it provides Hot-Resize and advanced file-moving algorithm to help resize hard drives without interruption and much faster.

If you have shrank drive D, you can move Unallocated space from right to the left side with 1 step:

Download NIUBI Partition Editor, right click drive D and select “Resize/Move Volume”.

Move drive D

Drag the middle position rightwards in the pop-up window.

Drag to move

Unallocated space is moved to the left side (behind C drive).

Tip This program is designed to work in its own virtual mode, so real disk partitions won’t be changed until click Apply to confirm.

How to add Unallocated space to C drive

When the moving operation is completed, you may either add the Unallocated space to C drive in Server 2008 Disk Management or continue with NIUBI.

Right click drive C and select Resize/Move Volume again, drag the right border rightwards to combine Unallocated space into C drive.

Extend C

C drive is extended to 50GB, click Apply on top left to execute, done.

If you have not shrank drive D with Disk Management, you can produce Unallocated space behind C drive with 1 step.

Similarly, right click D drive and select Resize/Move Volume feature, drag the left border rightwards in the pop-up window.

In Summary

To add Unallocated space to C drive in Windows Server 2008 R2:

  • When there is adjacent Unallocated space on the either side, drag the border towards other side in the pop-up window.
  • When the Unallocated space is nonadjacent, drag the middle position towards other side to move it.
  • If the entire hard disk is small and there is not enough free space in all other partitions in the same disk, clone to another larger disk. For example: if you clone 1 512GB disk to a 1TB disk, the 512GB extra space is Unallocated. You can move and merge the Unallocated space to C drive and/or any other volume.

Besides shrinking, moving and extending disk partitions, NIUBI Partition Editor helps you do many other conversion, optimization and management operations.
