Disk Management Failed to Extend Volume

"I have partitioned my Seagate hard disk into 4 partitions on my PC when installing the Windows Server 2003 operating system. Unfortunately, I only allocated 20GB space to C drive and now I want to reallocate more space to it. However, after clicking C drive under Disk Management, there is no Extend Volume option. Is there any other way to extend Windows Server 2003 C drive?"

"Extend Volume option is grayed out when I want to extend C drive space on Windows Server 2008 under Disk Management. There is about 30GB unallocated space which display behind D drive. How can I add the unallocated space to C drive on Windows Server 2008?"

How to Extend Volume under Disk Management?

For example, Disk Management in Windows XP and Windows Server 2003 does not have the function of extending volume. Besides, even if the Windows OS supports to extend volume under Disk Management, you should meet the following requirements,

1. There is unallocated space on the same hard disk
If there is no unallocated space, you can shrink other partition by selecting "Shrink Volume" option under Disk Management.

2. The unallocated space must display behind the partition you want to extend
Usually, you can extend C drive (system partition, primary partition, boot partition) and data volume under Disk Management on Windows 7, Windows 8, Windows Server 2008, Windows Server 2008 R2, Windows SBS 2008, Windows Server 2012, Windows Server 2012 R2 and more.
