Question on bios setting from raid to ahci Tags: Chipsets NAS / RAID Hewlett Packard Hard Drives Motherboards Last response: December 2, 2012 4:18 AM in Motherboards Share iaengineer December 2, 2012 3:45:47 AM I have an HP M9360f, with Core2 Quad Q9300 @ 2.50 GHz, and 1333 Mhz. It was orginally setup with two 500 GB hard drives in RAID configurations. Both of these hard drives failed, so I have removed them and installed a single Seagate 2 TB hard drive. I loaded the install disks, and when Windows goes to boot up, it gives an error. In searching online, it seems this is because it is still in RAID mode, and there is onlyl one drive now. I went into the setup, under Advanced, and see that I can change the SATA1 Controller Mode from RAID to AHCI. From my online search, it appears this change can create other problems, and some of them difficult to recover from. My question: Can I change to the AHCI mode, and if it doesn't work, easily get back into setup and change it back to RAID?
