    RAID (Redundant Array of Independent Disks) technology to recover data in the event of drive failure. HP now offers a simple RAID solution for notebook computer users who need to protect data on a Serial ATA (SATA) disk drive in case of drive failure or virus attacks. HP’s RAID solution also benefits computer users who frequently work with large files and want to improve the storage performance of their computer.

    Enable RAID using the Computer Setup (BIOS) (f10) NOTE: The following procedures assume that you are using the hard drive image that shipped with your computer. If a different image is installed on your computer, you must first enable RAID through the Computer Setup (BIOS) (f10), and then install the operating system and all required drivers, including the Intel Rapid Storage Technology driver.
  • Page 20 In the Device Configurations window, select RAID under SATA Device Mode. Click Confirm. The following message is displayed: “Changing this setting may require reinstallation of your operating system. Are you sure you want to proceed?” NOTE: The hard drive image supplied with your computer contains drivers that allow you to switch between AHCI and RAID modes without reinstalling the operating system.
