Hi Everyone im new to using Forums

SPECS
Motherboard- Asus p9x79 LGA 2011
Cpu- Intel Core i7-4820k
Ram- 4X4 16GB corsair vengeance
Graphics- 2X XFS 280x In crossfire
Storage- 2x Samsung Evo 250GB SSD In raid
2nd Storage- WD Red 4TB (yes i know its a nas drive)
OS- Windows 8

OK so a while ago i built a NAS i have since moved house and no longer need storage on the network so i backed up the drive and formatted it and installed it into my computer only to find out that i cant see the drive so i then went into disk management and formatted the drive as GPT now i have read a few of the forums on here and tryed just about everything in them but i cant seem to get windows to recognise the hard drive as anything other then 1.6TB When it is 4TB

*I believe installing the Intel RSTe was the fix:
https://downloadcenter.intel.com/confirm.aspx?httpDown=http://downloadmirror.intel.com/22502/eng/IATA_ENU.exe&Lang=eng&Dwnldid=22502

It's possible WD has its own software or the latest non-Enterprise of Intel RST will work as well.

Also, I didn't look any closer at your motherboard to see which controllers you had so it's possible this fix doesn't work for all SATA controllers if you have more than one (SATA connectors on motherboard that use the same controller are the same color).

Yeah i Was Thinking that myself so i checked and i am running UEFI windows and my motherboard is UEFI
Thanks
 
I had a similar problem when I had to install my a 3TB boot drive for a friend.
1. I know you checked buy are you super sure you installed the UEFI version of windows. I didn't know that there was a separate install option at first. The link below shows how to check.

2. Make sure you install the f6 intel RAID driver during install. You can keep it on a serperate drive or USB stick. It doesn't need to be on a floppy.

That solved it for me.
