Thus, users who encountered problem of low disk space always had no
solution. In the past users could only solve this problem indirectly by converting
dynamic disk to basic with Dynamic Disk Converter, then resize it with some partition
manager. About this method you could refer to this article “Three ways to convert dynamic disk to basic”. Today we will
not discuss this obsolete method any more, resizing dynamic disk directly with AOMEI Partition Assistant Server become a new hot topic. First
let’s learn some limitations of the built-in Disk Management (DM) on resizing dynamic
disk.
Limitations of Resizing Dynamic Disk in Windows
Dynamic disk helps users maximize data storage performance, especially for small
business company. But there is still two major disadvantage of it. When users
convert a basic disk to dynamic, it is impossible to convert it back in Disk
Management without data loss. Besides, in most conditions, users cannot resize
dynamic disk volumes, especially the system volume. In editions before Vista, users
were not able to resize dynamic disk conveniently. They can only extend certain
types of dynamic volume in Disk Management. List bellow is even impossible to
realize:
As you see, there are so many limitations of Disk Management(DM) on managing dynamic
disk, it integrate only a little basic functions, such as create/delete volume,
format volume. Obviously, this can't meet our requirements. Therefore, AOMEI Partition Assistant Server gradually comes into user’s
sight for its powerful function and fresh interface.
Resize Dynamic Disk with AOMEI Dynamic Disk Manager
As we know resize dynamic disk contains extending volume and shrinking volume. How to extend
system partition maybe the most visible user concerns.
Here we have an example based on Windows Server 2003, the existing volumes
listed below:

As you see, in this example the system partition (C :) is too small (only 3GB) and
we cannot resize dynamic disk by the built-in Disk Management. Let’s see how to solve
this problem with AOMEI Dynamic Disk Manager.
Note: To increase system partition, there must be a continuous
unallocated space behind system partition, we could shrink other volume to generate
unallocated space then move it to the right place.
Step1. Launch AOMEI Partition Assistant Server, click Dynamic Disk button to open its built-in uitlity, Dynamic Disk Manager. And then right-click drive E,
select “Resize/Move volume”.

Step2. In the pop-up window, drag right slider leftwards to shrink volume.

Step3. Position the mouse on the panel; drag it rightwards when the mouse
changes to cross. Then click “OK”.

After that you will find there’s an unallocated space behind system drive (C :).
Step4. Right-click system volume (C :), select “Resize/Move volume”,
in the pop-up window drag right slider rightwards to increase system volume size. Then
click “OK”.

Step5. Finally, click “Commit” on the toolbar to apply the pending
operations.
Note: To resize dynamic disk, in order to protect the system volume, the
operation will be completed in Reboot Mode, therefore, rebooting is necessary. The
software will require for rebooting after click “Commit”. After waiting
for some time (the time it cost is depend on the numbers of data on the volume which you
want to resize, the more data on it the longer time it will cost), you may find the
dynamic disk is resized successfully.
