Extend Volume grayed out in Server 2008-How to Solve

Since Windows 2008 built-in Disk Management contained Extend/Shrink feature, extending volume should have been never a problem in theory. However, sometimes we still cannot extend a volume in Server 2008. I think most of you may have encountered this condition: When Windows system drive is full, you propably think about using Disk Management to extend it. however, when you right click one volume and the “Extend Volume” option is grayed out in Server 2008, which means this function is not available.

Most of you may wonder why you aren’t allowed to extend partition with Disk Management in Server 2003 or in what situations this function can be highlight. The answer is that there must be an unallocated space contiguous behind the partition you want to extend, otherwise the Extend Volume gray out. So before you use this tool in Server 2008, please pay attention to contiguous unallocated behind it. If you just cannot meet the requirements it requires, how to do that? Here we introduce you an easy way to solve “extend volume greyed out” in Server 2008 disk management. 

Extend volume grayed out

Furthermore, if you use Disk Management, you can only extend partition with unallocated space behind the partition to be extended. If there is no unallocated space, the Extend Volume option will be grayed out, and even Diskpart unable to extend the volume. In that case, you need to use third party server partition software to extend volume.

Extend C drive with magic software

You may feel upset. In fact, it is possible to extend system partition (C:), but to activate "Extend Volume" option should be in some conditions. As there is no "contiguous unallocated space" after the (C:) partition drive, so in Windows Server 2008 “Extend Volume"  is greyed out. What can you do?
