How to divide partition into two on Windows 2008 Server

All disk partitions have been allocated while building the server, is it possible to change their partition size, divide a partition into two without formating or reinstalling operating system? In this article, I'll talk about dividing partitions in Windows 2008 Server.

Why divide a partition

Most of the Server administrators are not satisfied with factory partition setting of a brand Server. System C drive is too small while data partition is too large.

Some people forget to create more partitions when installing Windows, they installed Operating System to C drive with whole space of the hard disk. No one wants to start from scratch, reformat and reinstall OS.

It is a good habit to keep more partitions on a hard disk drive, for example, one for Operating System, one for applications and others for data, benefits as

  • System partition won't become full very quickly.
  • Saving different types of files in seperate partitions, you can read and manage files faster and easier.
  • Save large amount of small files in a big partition, it'll waste plenty of free space. Because the larger a partition formatted, the larger clusters are created.

Few administrators notice the disk space waste, here I want to give more details.

A file is saved in a sector(s), a cluster contains several sectors and cluster is basic unit for a file. The bigger a file is, the more clusters are used. Meanwhile, no matter how small a file is, all sectors of a cluster is reserved for the file.

File cluster sector

For example, a small file used sector 1 of one cluster, the space of sector 2 and 3 are wasted. Another file used 5 clusters, but only sector 1 of cluster 5 is used to save information, of course the space of sector 2 and 3 are wasted, too.

A sector is 0.5KB, if the cluster size of a partition is formatted as 32KB (64 sectors), a file is 1KB, so when it saved in this partition, 31KB disk space is wasted. Have you calculated how many files are there in your partition? (Generally, a partition is formatted as 4KB)

Then is it possible to divide a partition in Windows 2008 Server? Yes, it is.
