I have an ASUS p5ke-wifi/ap which has built-in RAID controller. From the BIOS, I can choose between 3 controller types:
IDE RAID AHCI
In that order. This setting was set to AHCI when I installed Windows7 Pro x64 and everything's fine. I have 3 hard drives, one is Windows7, and the other two I want to configure in RAID1/mirrored configuration, like this:
HDD1: Win7 HDD2: RAID Member1 HDD3: RAID Member2
Now, I've already installed Windows7, but it does not boot up when I set the controller to RAID from the BIOS. While in RAID mode, I was able to create a mirrored array from HDDs 2 and 3, and in AHCI mode Windows7 seems to recognize them perfectly as 1 disk drive. Is RAID a superset of AHCI - do I even need to set the controller to RAID mode?
I've been reading that you have to install Windows7 while in RAID mode for it to force the RAID drivers to install. Yet it seems to work without this.. so I'm not sure if it's software or hardware RAID.
Is this correct setup? How do I know whether this is hardware raid or Windows7 self-configured to see them as software RAID? Can I run my RAID configuration with the BIOS set to AHCI mode or does it have to be RAID? Thank you.
