Extend partition in Windows Server 2016 safely

It is not an easy task to expand disk drives for many computer users, even for some server administrators. Two reasons:

  1. Do not know how to do this, is it very difficult?
  2. Do not know which tool/software is the right choice, because a bad tool may cause system failure or partition corruption.

Windows Server 2016 has been released, more and more users ask how to extend volume on Windows 2016 Server. So in this article I’ll answer the questions and give detailed steps how to extend Server 2016 partition.

Is it difficult to extend partition on Server 2016?

Actually, it is very easy. Either Windows Disk Management or 3rd-party software provide graphic user interface. Server 2016 Disk Management provide Extend Volume Wizard to expand partition within few steps. However, there are many limitations of Disk Management and I’ll explain in next paragraph.

Server partition software is much easier to use by dragging and moving. It is much more powerful, too.

Which is the right tool to extend server volume?

It is hard to say, because everybody has his own choice, but to me NIUBI Partition Editor is better, why?

  1. The unique software that integrated 1 Second Roll-Back technology, what’s that? This technology is able to automatically roll back the server to the status before resizing in ONE second, if software related error or hardware issue such as powerful failure occur during resizing partitions. So no longer to worry about Operating System and data safely. It is tremendous innovation in disk management industry.
  2. The unique file-moving algorithm helps resize partition 30% – 300% faster than any other tools. Saving much time especially when there are large amount of files in the partition that you want to resize.
  3. Extend NTFS partition on the fly without rebooting server. (close other running applications before starting this program)
  4. To avoid mistake, all operations work in virtual mode before clicking Apply to execute. You can preview, cancel and redo any steps.
