How do I create a mirrored volume in Windows XP (or Windows 2000 Pro)?
A mirrored volume, also known as a RAID-1 volume, is a fault-tolerant volume that duplicates data on two different physical disks. Mirrored volumes are supported on dynamic disks, and provide data redundancy by using two identical copies (mirrors) of the volume.
You cannot create mirrored volumes on computers that are running Windows XP Home Edition, Windows XP Professional, Windows 2000 Professional or Windows XP 64-Bit Edition.

You must have administrative privileges on the remote computer to do this.
