Overview of primary partition
A primary partition is the volume where operating system can be installed. For MBR style disk, it can hold up to four primary partitions. For GPT style disk, it is able to hold 128 primary partitions at least. Active partition is based on primary partition. There can be 4 primary partitions and only one active partition. Any primary partition can be set as active partition that contains boot loader to load operating system. A primary partition can be a drive that operating system is installed on or a drive that stores regular data. General speaking, only one primary partition is necessary, which is known as C: drive.
When need to extend primary partition Windows Server 2008 (R2)?
As time goes on, more and more applications have been installed on Windows Server 2008 (R2) hard drive and the primary partition is lack of space. What’s worse, the warning “Low Disk Space” may present. You can find that the running speed of machine is lower and lower and the applications even don’t react when you click icon of some applications. In such case, you can extend Windows Server 2008 (R2) primary partition to get the machine back to normal situation. The next part will show how to increase primary partition size on Windows server 2008 (R2) primary partition.
Extend primary partition on Windows Server 2008 (R2) via Disk Management
Disk Management is a tool built in Windows Server 2008 (R2) and it allows you to shrink and extend partition. It is available to quickly access Disk Management by “pressing Windows +R” and typing diskmgmt.mscand hitting “Enter”. You can increase the primary partition size when there is unallocated space just right behind the primary partition; otherwise, you will find out that Windows Server 2008 (R2) “Extend volume” grayed out. Here recommend you to apply proper third party software to extend Windows Server 2008 (R2) primary partition.
When you’re insisting to extend primary partition C: drive with Disk Management, you can refer to the following instruction.
1. In order to get unallocated space right behind the primary partition C: drive, you have to delete primary partition D: drive (backup important data before deleting).
PS: If the partition right behind C: drive is an extended partition, you have to delete all the logical drives on the extended partition. Then delete the extended partition to get an unallocated space for extending C drive.
2. Then, it is able to increase C: drive size with Disk Management. Click C: drive and choose extend volume.
Both free space and unallocated space and unallocated space refer to storage space that doesn’t hold data in different ways. Free space can’t be used to extend primary partition and unallocated space can’t be applied to extend logic partition.
If you are familiar with Windows command prompt, you can extend partition with Diskpart. But this also demands an unallocated space contagious to the partition you need to extend.
