Extending your Server 2003 Disk Partitions using Dell Extpart

So we all know that we should be migrating away from Server 2003 as its end of life June 2015. But until then we still need to manage it.

So lets look at how to extend your hard drives into unpartitioned space using the Dell Extpart tool.

Note: This is probably not supported by VMware, so use at your own risk

So create your unpartitioned space, i.e in VMware, extend the hard drive.

Rescan your disk in Computer Management so the unpartitioned space appears. Right clicking on the drive, you will see there is no extend option, as found in Server 2008 and up.


Download the Dell Expart tool from this link;


Run the .exe file which will extract to c:\dell\

  • Open up Command Prompt, change to the extracted location.
  • Run the extpart tool
  • Select your drive and then the space you need to extend by (unpartitioned space x 1024)

Here you can see the screenshots from my environment to perform this task.
