You must be logged on as an administrator or a member of the Administrators group in order to complete this procedure. If your computer is connected to a network, network policy settings may also prevent you from completing this procedure. 

You can create mirrored volumes only on computers running Windows 2000 Server, Windows 2000 Advanced Server, Windows 2000 Datacenter Server, or .

You need two dynamic disks to create a mirrored volume.

You can mirror an existing simple volume.

Mirrored volumes are fault tolerant and use RAID-1, which provides redundancy by creating two identical copies of a volume.

Mirrored volumes cannot be extended or striped.

Both copies (mirrors) of the mirrored volume share the same drive letter.

Using a command line

1.

Open Command Prompt

2.

Type:

diskpart

3.

At the DISKPART prompt, type:

list disk

Make note of the disk numbers for the dynamic disks that will make up the mirrored volume.

4.

At the DISKPART prompt, type:

select disk n

If the disk is empty, continue to step 5 to create a simple volume on that disk. Otherwise, proceed to step 6.

5.

At the DISKPART prompt, type:

create volume simple [size=n] [disk=n]

6.

At the DISKPART prompt, type:

add disk n

ValueDescription

list disk

Displays a list of disks and information about them, such as their size, amount of available free space, whether the disk is a basic or dynamic disk, and whether the disk uses the master boot record (MBR) or GUID partition table (GPT) partition style. The disk marked with an asterisk (*) has focus.

select disk

Selects the specified disk, where n is the disk number, and shifts the focus to it.

create volume simple

size=n

The size of the volume in megabytes (MB). If no size is given, the new volume takes up the remaining free space on the disk.

disk=n

The dynamic disk on which to create the volume. If no disk is given, the current disk is used.

add disk=n

Mirrors the simple volume with focus to the specified disk, where n is the disk number. The specified disk must have unallocated space at least as large as the size of the simple volume you want to mirror.
