Hi all, I'm running into a snag with setting up my new 4 x 4TB HDDs in Raid 5. I recently purchased the HDDs and have spent the past few days trying to set them up correctly. When I set them up in Intel Rapid Storage Technology's enterprise (Intel RSTe) as Raid 5 they work perfectly, showing me that Raid 5 is in parity with ~10TB of total storage across the drives.
Afterwards, when I log into Windows 8 and go through the Disk Management system, setting the drives up as Dynamic and GPT, they only appear as ~1.6TB in size.
The same issue persists when I go to Storage Spaces to try and Raid them that way.
I've updated my BIOS to the most recent version, Enabled Raid in the BIOS, tried to install updated versions of the Intel RSTe (it says my operating system is not compatible or that I have the most recent version) and tried to install updated versions of Asus' Sata Drivers (says I have the most recent version).
It seems like a simple driver issue since the Intel RSTe recognizes the Raid 5 but Windows does not. Any suggestions?
My specs:
Windows 8
Asus P9X79 with most recent BIOS (4701)
i7 3930 @ 3.2GHz
16GB Ram
2 x 240GB Corsair SSDs (Operating System)
4 x 4TB Western Digital Blacks HDDs (Data)

Did you confirm that each HDD was 4TB to start with? They could of had a mistake sending them to you.What is the model number on the HDDs to double check and to check if maybe this is a known issue if they are 4TB
They are all 4TB WD4003FZEX. I haven't seen persistent issues with this particular drive elsewhere. Also, I tried to Raid 0 two separate 4TB drives and the resulting total storage was still only ~4TB. This seems like a strange upper limit given my technical specs and 64bit OS.
Thanks for the reply IInuyasha74.

No problem, just hope we can figure this out. Give me a little while, if someone else comes and knows that is great, but I'm not sure what the problem is. So I am going to search around about your motherboard, drivers, the HDDs, etc. see if I can't find anything.

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 8.6.2.1022 (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.
Suggestions...?

Best solution
Yea I had went looking but couldn't find anything outside of possible driver error, and I know you had already started looking into that so I didn't want to comment without having something to offer.
Anyways, if you know which specific driver its best you go download that one from Asus and try installing it. If it fails to install or it installs but doesn't fix the problem, you could then try a manual install from Device Manager, same place you were earlier. Though its possible Intel has been lazy about updating the driver for i and all Asus did was keep updating minor things about the file to help it install but without actually changing the driver.

So it seems it was a driver issue!
Solution: Install the latest Intel® Rapid Storage Enterprise (IATA_ENU.exe) available on intel's download/support page, and ignore the prompt which tells you that you have the most up-to-date driver.
I failed to ignore the prompt and didn't install the driver since the prompt told me that I already had the most up-to-date driver.
Thanks IInuyasha74.
