Hardware RAID5 Broken after Windows 8 Install

First, I'll break down my system. I hada 64 GB SSD with Windows 7 installed on it . I also have 3 1TB hard drives set up in a RAID5 through the hardware RAID controller, so all windows saw was a single, 2TB hard drive, used for storage.

I then decided to get ambitious and replace the SSD with a larger, 225GB one and install Windows 8 on that. I installed by booting from a USB drive. When the screen with the drive selection came up, I made sure to select the new SSD and I didn't touch the RAID5 array (which windows 8 install still saw as 1 2TB disk).

Install finishes, I reboot, and I see that Windows 8 now sees the RAID5 Array as 3 1 TB disks, displayed as follows

DISK 0 (Online) - RAW (Primary Partition)
DISK 1 (Not Initialized) - Unallocated
DISK 2 (Online) - No partition, but not listed as "Unallocated"

I have been very careful not to do anything that could possibly perform a write operation on any of these drives. I've run TestDisk numerous times, on all 3 drives, but haven't made any changes as it only finds a lost partition on the 3rd disk, but I feel like it shouldn't be viewing the 3 drives separately, so I opted against trying to recover the partition.

Any help would be greatly appreciated.

    Download and install the latest Intel RST drivers in your OS and it should detect the array correctly, you can get them HERE.

    It's the built in one in my motherboard. Motherboard is an ASUS P5VDC-X, the southbridge chip which handles the RAID is VIA VT8237A

    Thanks, but I don't think my controller is Intel based. I just tried to run this and got error "This platform is not supported"
  5. Thank you both so much. Turns out I needed to update the chipset drivers afterall. I actually have a gigabyte motherboard (was thinking of an older box when I said it was the ASUS) and once I downloaded the chipset drivers and installed them, I was able to access the array just fine. I certainly wouldn't have thought to go down that path if it wasn't for the suggestions made by you, thanks!
