Mirroring Dynamic Disks with RDR

This procedure turns dynamic disks into basic disks before mirroring them with RDR.

To use RDR to mirror dynamic disks themselves, see Chapter 3 in the

Express5800/320Ma: Software Installation and Configuration Guide.

Mirroring a dynamic disk with RDR involves two steps:

• Converting the disk to basic

• Upgrading the disk to RDR

Converting a Dynamic Disk to a Basic Disk

CAUTION

Converting a dynamic disk to a basic disk removes all

data from the disk. So that you can recover the data, back

it up to backup media before you convert the disk to a

basic disk.

1. Right-click My Computer, and click Manage.

2. Expand Computer Management and Storage.

3. Click Disk Management.

4. Right-click the icon of the target disk in the lower portion of the Disk Management

details pane.

5. Select Convert to Basic Disk.

6. If necessary, recover the information from backup media.

To upgrade the basic disks to RDR, see “Notes on Using RDR to Mirror Disks in

Internal Storage” on page 4-5.
