As we know mirrored volume is a type of dynamic volumes. Because of its perfect fault tolerance, it is widely used on those computers which require higher data safety, such as server computer. As is well known server computer often stores a large number of important and commonly used data. Once these data are lost, server users will bear great losses. Therefore, using dynamic mirrored volume with extremely high fault tolerance on server is a good choice. However, when users operate dynamic mirrored volume on server computer, they may meet many problems. For example, when storing important data, they can not store these important data because of space shortage of mirrored volume. Well then, what should they do if mirrored volume is badly in need of space? The answer is very simple, namely extending dynamic mirrored volumes. I suggest using MiniTool Partition Wizard, a perfect dynamic disk manager, to extend mirrored volumes of dynamic disk. That is because the latest edition of MiniTool Partition Wizard not only can be compatible with dynamic disk perfectly but also can help users manage any type of dynamic volume perfectly, such as simple volume, spanned volume, striped volume, and Raid-5 volume.

The precondition for creating mirrored volume
If we want to create mirrored volume with high fault tolerance on our computers, we should meet two conditions:
1. The disk is dynamic disk: As mirrored volume is one type of dynamic volumes, we must convert basic disk to dynamic disk at first if we want to create mirrored volume. The method for converting basic disk to dynamic disk is very easy. We right click the very partition needing upgrading in Windows built-in disk management tool, and then select "Convert to Dynamic Disk…" in the shortcut menu to enter the wizard. At this time, we only need to operate according to prompts.
2. At least 2 disks are needed: when dynamic mirrored volume stores data, it needs to write data in two different disks simultaneously, which is used to offer fault tolerance. When data in one disk are damaged, we can restore them through the same data in the other disk. This feature of mirrored volume requires that the spaces constituting mirrored volume must come from 2 different disks with the same capacity. Therefore, if users want to create a dynamic mirrored volume, they at least need 2 disks.
After meeting the above two conditions simultaneously, we can create mirrored volume on our computer easily.
Extend dynamic mirrored volume with MiniTool Partition Wizard
Extending mirrored volume is a kind of commonly seen dynamic volume management. Methods for realizing this operation are different for different people. Among these methods, extending mirrored volume of dynamic disk with MiniTool Partition Wizard is the most commonly seen methods. If users want to use this dynamic disk manager, please visit its official website to download it and install it on your computer. With running this dynamic disk manager, we can see the following main interface:
In this interface, we right click the mirrored volume needing extending, and then select "Move/Resize" in the pop up menu. Next, we will see the following interface.
Here, we can extend mirrored volume by dragging triangles on both sides of the partition handle to change length or inputting exact values. After finishing settings, we click "OK" to go back to the main interface:
In the above interface, we click "Apply" to perform all operations. When performing operations, this dynamic disk manager requires restarting the computer:
At this time, we click "Restart Now" to restart the computer. After finishing restart, we will find the mirrored volume has been extended successfully.
Although dynamic mirrored volume has extremely high fault tolerance, it is still not perfect. Dynamic mirrored volume does not have any promotion in performance, and fault tolerance is acquired at the price of losing disk space. Therefore, we must pay much attention to using it. For those users who require higher data safety, they can manage mirrored volume with MiniTool Partition Wizard when they use dynamic mirrored volume, thereby maximizing mirrored volume performance and space use ratio.
