Configuring Your Computer for RAID Using the Intel Matrix Storage Manager If you already have one hard drive with the operating system installed on it, and you want to add a second hard drive and reconfigure both drives into a RAID volume without losing the existing operating system and any data, you need to use the migrating option for a RAID level 0 configuration (see "Migrating to a RAID Level 0 Configuration" on page 301) or a RAID level 1 configuration (see "Migrating to a RAID Level 1 Configuration" on page 301). Create a RAID level 0 volume or RAID level 1 volume only when: • You are adding a new drive to an existing single-drive computer (and the operating system is on the single drive), and you want to configure the drives into a RAID volume. • You already have a two-hard drive computer configured into a volume, but you still have some space left on the volume that you want to designate as a second RAID volume. Creating a RAID Level 0 Configuration NOTE: When you perform this operation, all data on the RAID drives will be lost. 1 Set your computer to RAID-enabled mode (see "Setting Your Computer to RAID-Enabled Mode" on page 297). 2 Click Start and point to Programs→ Intel(R) Matrix Storage Manager→ Intel Matrix Storage Console to launch the Intel Storage Utility.

To add a third hard drive in your RAID level 0 volume, click the right arrow and click the third drive until three drives appear in the Selected window, and then click Next. Advanced Features 299
