About dynamic mirrored volume

A mirrored volume, also known as a RAID 1, is a fault-tolerant volume that duplicates data on two different physical disks. Mirrored volumes are supported on dynamic disk in Windows Server 2000, 2003, 2008, 2011, 2012 and the latest Windows 7/8, and provide data redundancy by using two identical copies (mirrors) of the volume. If one of the disks fails, the data can still be accessed from the remaining disk.

Ways to extend mirrored volume on dynamic disk?

In the past, the most commonly used method is to convert dynamic partition on mirrored volume to basic first, and then extend basic disk partition with AOMEI Partition Assistant.
