A mirrored volume, also known as a RAID-1 volume, is a fault-tolerant volume that duplicates your data on two different physical disks. Mirrored volumes are supported on dynamic disks, and provide data redundancy by using two identical copies of your drive.

Below I will give you the steps in setting up a mirrored drive on a Windows 2003 System.

 

  1. Log on to the system with Administrator rights.
  2. Click Start and then right click My Computer.
  3. Then click Manage.
  4. In the Disk Management window, right-click the drive that you want to mirror, and then click Add Mirror.
  5. Click the disk in which you want to use to mirror, and then click Add Mirror.

Note: you cannot create mirrored volumes on computers that are running Windows XP Home Edition, Windows XP Professional or Windows XP 64-Bit Edition
