SATA hard drives can run in three different modes: IDE, RAID or AHCI. IDE -- the old interface standard for hard disks and optical drives -- is compatible with a variety of platforms, including Windows XP, Windows Vista and Windows 7. AHCI includes features not accessible from IDE mode but is compatible with only Windows Vista and Windows 7. RAID mode allows a user to configure multiple disks for advanced performance or backup security.
The BIOS set-up menu, accessible from the boot screen, allows you to configure your hard drive's mode.
