Dynamic disk is a kind of physical disk supported by Windows 2000 and later Windows OS. And it provides lots of features basic disk does not have, like the ability to create fault-tolerance volumes. Besides, dynamic volumes can be extended from another physical disk, which gets better use of disk space. Dynamic volume includes simple, spanned, striped (RAID 0), mirror (RAID 1) and RAID 5. No matter which kind of volume you use, it is important for you to learn how to resize dynamic disk if you want to make good use of the disk space.

How to Resize Dynamic Disk?

When you store too much files and data on a dynamic volume and there is not enough space, you may need to add some free space from unallocated space on the disk or from another disk to store more data. However there is a good chance that you don’t know how to resize dynamic disk. In this post, I offer you two ways to resize dynamic disks, which can help you extend dynamic volume or shrink dynamic volume effectively.

Resize Dynamic Disk in Disk Management

Step 1. Right-click the Windows Start menu and choose Disk Management.
Step 2. Select the volume you want to resize and right-click, choose Extend Volume feature or Shrink Volume feature to resize dynamic disk. For example, if you want to extend dynamic disk, you may choose Extend Volume. Then click Next.
Step 3. Type the volume size that you want to extend in MB. Then click Next.
Step 4. Click Finish and you will find the dynamic volume has been resized.
However, you will only find the Extend Volume feature and Shrink Volume feature are available only in simple volume and spanned volume, as Disk Management can only extend or shrink simple volume and spanned volume. So, Disk Management is not our best choice anyway if we want to extend a mirrored volume, striped volume, or RAID 5 volume.
To break the limitation of Disk Management and shrink or extend dynamic disks in a simple and convenient way, here I will recommend you a third party software to resize dynamic disk: MiniTool Partition Wizard.
