It is well known that mirrored volume is one of the five types of dynamic volumes A
mirrored volume (also known as RAID 1) is a fault-tolerant volume that duplicates your
data on two separate dynamic disks. A mirror provides redundancy by writing the same
data simultaneously. If one of the physical disks fails, the data on the failed disk
becomes unavailable, but the system continues to operate using the unaffected disk.
Mirrored volumes are supported by Windows Server 2000, 2003, 2008, 2011, 2012 and
the latest Windows 7/8.
Because of the fault-tolerant advantage of mirrored volume, it is widely used by
those who require high performance and high safety of computer, such as server
administrators. However, with the quantity of important data stored on mirrored
volume increasing, mirrored volumes will be running out of space. In this condition,
you have to extend mirrored volume to include more data and files.
Unfortunately, Windows built-in disk tool can only extend simple and spanned volume,
excluding mirrored volume. If you want to increase mirrored volume space, professional dynamic disk
manager is indispensable, such as Partition Assistant, which is special
designed to resize volume on both dynamic and basic disk. This tool can help you
extend simple/spanned/striped/mirrored/RAID 5 volumes. Here is an example of how to
extend mirrored volume safely and easily.
Extend mirrored volume with Partition Assistant
Note: To extend mirrored volume, there must be some unallocated
space on two disks, otherwise, you need to shrink
volume or delete volume to generate.
Step1: Open this software to get its main interface.
Step2: Launch AOMEI Dynamic Disk Manager, right-click mirrored
volume and select "Resize/Move" option in the drop-down
Step3: In the pop-up window, drag the right slider rightwards
to extend mirrored volume into unallocated space. Then, click
Step4: You can preview the mirrored volumes has been extended.
To save the changes, you need to click "Commit" on the
From the demonstration above, you can see it is easy extend mirrored volume with
software. So please free download it and try it immediately.
