Solutions - Two Ways to Resize Partition Windows Server 2003

In dealing with this scenario, here are two viable options, using the Windows DiskPart Command Line and the more reliable and easier newest server disk partition software. We will give detail step-by-step instructions of resizing Windows 2003 partition.
The Small System Partition before Extending
  • Download: download the Server trial version (The trial version allows you to experience all the features of the partition magac server software before purchasing)
  • Installation: It only takes less 10M capacity to install.
  • Environment: Windows Server 2003 R2 Enterprise X64 Edition.
  • Task: Enlarge the C system partition (9GB) to ideal size on Disk1.

1. Launch the program, we get the below window, it displays the main features set in left panel, disk partition information and running environment.

Main Interface

Resize Move Partition Option

Shrink Continuous Data Partition

2. Right click D partition and choose "Resize/Move Partition" option, in the new window, drag the left side to right to allocate more free space.

3. Back to the main window, right click C system partition and choose "Resize/Move Partition" option, drag the right side to left to add the unallocated space that that released from D partition in previous procedure.

Extending System Partition

Enlarged System Partition

4. Finally, commit those changes by clicking the "Apply" button. And we will see the result in Windows Disk Management. The system partition was enlarged to 35.33GB.

As well, we are allowed to use Windows Server 2003 built-in DiskPart.exe to extend a data partition (Don't include a system page file). Take the above forum problem for example, we are running the command-line.
  • Step1: Click "Start" > "Programs" > "Accessories" > "Command Prompt", type "diskPart" and press "Enter" to continue.
  • Step2: Type "list volume" to display the existing volumes on the disks.
  • Step3: Type "select volume 1". The number is the volume that you want to extend, (We choose Volume 1 system partition)
  • Step4: Type "extend size=10240".

Then you should receive a message states that DiskPart cannot extend the partition.

DiskPart Command Line

Using DiskPart to resize Windows Server 2003 partition is available under below certain conditions:

  1. It only supports NTFS file system
  2. Only DATA partition can be extended. Extending system or boot partition, there will be an error message "Diskpart failed to extend the volume. Please make sure the volume is valid for extending".
  3. There must be some contiguous unallocated space on the right side of the target partition which needs to be extended.

It allows you to perform basic or advanced disk & partition operations without losing data, deleting partitions and destroying Operating System.
