I think I've figured the issue, but I am still unable to resolve it: Since the Intel RSTe is recognizing the 4 x 4TB in Raid 5, I assumed that there was a driver issue somewhere along the way. After updating the BIOS to the most version and having the problem persist, I went through my Device Manager to try and locate the Storage Controller: Intel(R) C600 Series Chipset SATA RAID Controller. The SATA RAID controller is from 2010-08-07 and its Driver Version is 22.214.171.1242 (super old). However, when I try to update the driver, it tells me that I am using the most up-to-date version of the driver (I know it's not true since ASUS has a driver from 2013). Furthermore, when I try to uninstall the driver, it won't allow it.
Thanks for joining the Chipset community.
The latest Intel® Rapid Storage Enterprise version is available here: IATA_ENU.exe
Just make sure you have installed the latest version and if you get any prompt message, continue with the installation.
I would like to know if the Intel® Rapid Storage software is detecting your RAID 5 configuration, please take a screenshot of the Intel® Rapid Storage tool and attach it here.
Holy Moses! It worked! I tried to install that previous driver but didn't since the following prompt message came up:
As for the screenshot, you can view it in the original post, however, I will repost it here:
All in all it seems the best answer was as you suggested: "The latest Intel® Rapid Storage Enterprise version is available here: IATA_ENU.exe" and to proceed through the prompt.
Asus P9X79 Deluxe
Intel 3930K i7 3.2GHz
Windows 8.1 (at the time of my previous post, and Windows 7 before starting any upgrades)
I had since then upgraded to Windows 10/64bit to no avail. I was finally able to update chipset by updating Win10 and trying a few different installers. Still could not install ANY version of Intel Rapid Storage Technology. I then finally toggle one setting in my Asus BIOS under SATA config: Set the RAID type to IRST, rather than RSTe. I then could finally install the most recent Intel Rapid Storage driver. Upon plugging my 4-disk RAID 5 in and booting, 2 of the drives are "Missing" and RAID is failed.
I'm currently recovering my old Win7 to boot and try to fix the RAID. Once I get back to starting point, I have to figure out how to update a few systems in the office to Win10 (and chipsets/Bios/etc) without failing the RAID 5's in those systems.
