Learn to solve the problem the volume requires contiguous disk extents received in Disk Management or DiskPart when trying to extend a volume. Keywords:
When you are trying to extend a volume on a dynamic disk in Windows built-in tool Disk Management, you may receive the error the volume requires contiguous disk extents.
If you try this in DiskPart, you will receive the same error message Virtual Disk Service error:
The volume requires contiguous disk extents.
On basic disk, Windows Disk Management or DiskPart allows you to extend a partition only when there is contiguous unallocated space right behind the volume that you are trying to extend. When you actual have contiguous unallocated space on the left of the volume to be extended, you will see the Extend Volume option greyed out.
On dynamic disk, Disk Management is supposed to be able to extend volume as long as there is unallocated space no matter whether it is contiguous or not. Therefore, if you receive the DiskPart extend the volume requires contiguous disk extents error, there must be some uncertain reasons behind this error.
You can try one or more of the steps below to work it out:
1. Close all the programs that might affect the volume status.
2. Use the unallocated space to create a new volume and then delete it.
3. Restart your computer.
If the Extend Volume still fails after all these steps, you may consider reformatting the hard drive or trying third party software.
