A RAID 0 volume is reported as failed and a RAID 1 volume is reported as degraded when one of their member hard drives fails or is disconnected. When both a RAID 0 volume and a RAID 1 volume are on the same RAID array (i.e. matrix RAID), you may experience both a degraded RAID 1 and a failed RAID 0 at the same time.

In order to recover, you will first need to determine whether a hard drive failed or is missing.

• Missing hard drive
• Failed hard drive, OS on RAID 0 volume
• Failed hard drive, OS on RAID 1 volume
• Failed hard drive, OS on another non-RAID hard drive
• Failed hard drives

1. Power off the system.
2. Reconnect the missing hard drive.
3. Power on the system. During the system startup, the Intel® Matrix Storage Manager option ROM status screen should display a RAID 0 volume status of Normal and a RAID 1 volume status of Rebuild.

If you would like to monitor the progress of the rebuild, use the following steps.

1. Click Start.
2. Click Programs.
3. Click Intel® Matrix Storage Manager.
4. Click Intel® Matrix Storage Console.
5. Click the View menu and select Advanced Mode. When the RAID 0 volume is selected, the status should say Normal. When the RAID 1 volume is selected, the status should say Rebuilding % complete; when the rebuild is complete, the status will say Normal.

Failed Hard Drive, Operating System on RAID 0 Volume

1. Power off the system.
2. Replace the failed hard drive with a new hard drive that is of equal or greater capacity.
3. Power on the system. During the system startup, the Intel® Matrix Storage option ROM status screen will display a RAID 0 volume status of Failed and a RAID 1 volume status of Degraded.
4. Install an operating system on the new non-RAID hard drive and press F6 when prompted.
5. Use the F6 installation method to install the RAID driver.
6. After the OS installation is complete, open Windows Explorer* and identify the partition existing on the new hard drive and the partition existing on the degraded RAID 1 volume.
7. Copy the data you want to keep from the degraded RAID 1 volume onto the new partition. If you want to re-create your original configuration - a RAID 1 volume and a RAID 0 volume - continue with step 8.
8. Click Start.
9. Click Programs.
10. Click Intel® Matrix Storage Manager.
11. Click Intel® Matrix Storage Console.
12. Click the View menu and select Advanced Mode.
13. To delete the RAID 0 volume, right-click on the RAID 0 volume in the device tree and select Delete Volume. The volume deletion wizard will walk you through the deletion process.
14. To delete the RAID 1 volume, right-click on the RAID 1 volume in the device tree and select Delete Volume. The volume deletion wizard will walk you through the deletion process..
15. To create the RAID 0 volume, click the Actions menu and select Create RAID Volume from Existing Hard Drive. The volume creation wizard will walk you through the creation process. Select a volume size that is less than the array size in order to leave room for the RAID 1 volume.
16. When the RAID 0 volume creation is complete, click the Actions menu and select Create RAID Volume in order to create the RAID 1 volume. The volume creation wizard will walk you through the creation process.
17. Move any of your original RAID 1 data (now on the RAID 0 volume) back to this new RAID 1 volume if you wish.

Failed Hard Drive, Operating System on RAID 1 Volume or Other Non-RAID Hard Drive

1. Power off the system.
2. Replace the failed hard drive with a new hard drive that is of equal or greater capacity.
3. Power on the system. During the system startup, the Intel(R) Matrix Storage option ROM status screen will display a RAID 1 volume status of Degraded and a RAID 0 volume status of Failed.
4. After the operating system is running, click Start.
5. Click Programs.
6. Click Intel® Matrix Storage Manager.
7. Click Intel® Matrix Storage Console.
8. Click the View menu and select Advanced Mode.
9. To delete the RAID 0 volume, right-click on the RAID 0 volume in the device tree and select Delete Volume. The volume deletion wizard will walk you through the deletion process.
10. To create a new RAID 0 volume, click the Actions menu and select Create RAID Volume. The volume creation wizard will walk you through the creation process.
11. Use the Windows Disk Management* utility to partition and format the new RAID 0 volume.

Failed Hard Drives

When both hard drive members of a RAID 0 or RAID 1 volume fail, the error is unrecoverable.
