Hoping someone here can help me out...

I just built my first home server and having trouble creating a RAID-1 setup.

I am using a Asus mobo with RAID hardware and support for RAID-1. I have a 750GB primary drive where I have Windows Home Server 2011 installed (nothing else is on this drive but the OS).

What I want to do is add 2 2TB drives for my RAID-1.

1. When I boot up, I enter the BIOS and change the SATA Controller settings from IDE to RAID. I Save and let it re-boot.
2. In the BIOS, I confirm the Boot settings are DVD-Drive first, then 750GB primary drive
3. Then, I hit CTL + I to enter the RAID Volume setup, create a RAID1, select my 2 2TB drives and Save. I don't change any of the other settings.
4. Let it reboot again, and this is where I run into the problem. It appears to boot from one of the drives in the RAID volume so it does not pick up the OS.

Can anyone tell me what I am doing wrong? If I go into the BIOS and change the SATA Controller back to IDE, then it works fine.

Anyone?

Sorry, what i meant was I originally had it with DVD drive first, then 750GB drive. However, now I have it to boot from the 750GB drive only and not the DVD drive.

Go back in the BIOS and look for "Boot Order". Make sure the 750GB device is the first in the boot list. Some BIOS have boot devices the select between DVD/CDROM, network USB and hard drive boot as well as hard drive boot order to select which SATA device is booted first.

Hi, i did that and still having the same problem. It seems to automatically boot from the RAID volume instead of the 750GB drive.

That's because you have the boot drive on the controller that you just switched to RAID and your windows doesn't know how to boot from RAID. If possible, your boot drive needs to be on a different SATA controller (set to IDE) than the RAID controller, otherwise you will need to reinstall the OS and use the advanced feature during install to install the RAID drivers. This is basically like using the F6 feature during an XP install.

I think I only have 1 controller on my mobo. Does this mean i have to get a separate raid controller card?

If your motherboard only has one controller and it's set to RAID, you will need to reinstall your OS and programs. You can sometimes use a registry tweak to switch between IDE and AHCI or vice-versa, but switching from one of these to RAID or vice versa requires a clean install of the OS.

If I reinstall the OS after I set it to RAID, can I install it on the 750GB drive? Or do I have to install it onto the RAID drives?

You should still be able to put it on the 750g drive, but you may have to change the setup. The 750gig drive would need to be set up as a single drive RAID 0 array and you will need to install the raid drivers during the OS install when you have the option to install 3rd party drivers.

Are you sure your motherboard doesn't have two drive controllers? Most motherboards that support raid have two controllers. You can set the controller that contains your boot drive to AHCI and the controller that has the other two drives to RAID.
