Windows Small Business Server 2011 serves as one of the best operating systems for organizations. The added features and constant flow of updates make it an efficient office-oriented OS. However, these updates also lead to low-disk space and SBS 2011 also does not allow you to resize partitions at the time of installation. If you are reading this article, you might have been expiring the same problem. Tired of reading the old and complex articles to resize partition with CMD Diskpart? Well, I will try to explain each part as simple as possible so even a novice can get the job done within minutes.

What is CMD Diskpart

CMD Diskpart is a command line disk management interface that allows you to manage storage space, partitions, volume configurations, and more settings by direct input, remote session, and scripts. Diskpart is the underlying interface of the graphical user interface but it gives more access to the system tools. Though Diskpart prohibits you from employing operations that may cause data loss, it certainly offers complex methods to resize partitions.

Diskpart is, no doubt, complex as compared to most of command line tools because it cannot work on a single-line mode. In windows server 2011, you will only have to use the select volume, list volume, and extend volume commands to resize partitions. To resize the partition using CMD diskpart, follow these steps

Press windows+R and you will see the “Run” dialogue box at the left bottom side of the window

Type “cmd” and press enter, and the command line interface will open

Now type “Diskpart” and press enter. You will be redirected to a new window called “Diskpart”

Type “List Volume” and you will see the different options named as volume 1, 2, 3

Usually, volume 1 is listed as the system partition.

Enter the command “select volume1” and then enter “extend”. A dialogue “Diskpart cannot extend system partition” will appear.

Why Diskpart failed to extend the partition? That is because the system could not find the unallocated space next to the c-drive. To resize c drive, there must be unallocated space adjacent to the c-drive. Separating unallocated space from a data partition and placing it next to the c drive is impossible. And if possible, I would not spend my quality time dealing with commands and errors.

Therefore, it is recommended to either use built-in disk management utility. And if the unallocated space is not placed right next to c drive, then the only solution is to use a third-party partition resizer software.
