Folks, I have an Asus P6T Deluxe V2 MB using (all SATA drives) 2 - 2TB drives as RAID 1 boot drive, running Windows 7 64 bit. I also have my 2nd RAID2 (we will call it) as a data drive, 2 - 2TB drives as well, no issues at all... I've been running this configuration for some time. Last night, I swapped out the 2nd Raid (2-2tb data drives), and installed 2-3TB drives). Recap now I have my Boot Raid of 2 - 2tb drives, data Raid of 2 - 3TB drives.
When I boot up during POST, I see the Intel ICH10R Rom 188.8.131.528 shows my boot Raid as the 2 - 2tb drives, HOWEVER the 3TB drives show as 746.5 GB, which one I don't recall. ** however when I boot into Windows 7, 64 bit, the Operating System sees my drives all fine, the correct data size, period, no issue. Even prior to upgrading Intel RST to version 184.108.40.2063, Intels software still shows the correct size. I only upgraded RST to a slightly newer version, thinking perhaps it may initiate a change to the Intel ROM version, which I figured it probably wouldn't and it didn't. I realize typically ROM or BIOS updates run via a utility, etc.. (I work in IT for over 20+ years, so I am familiar).
I looked at ASUS Bios updates and was already running the version of BIOS update that stated about showing the correct/updated hard drive size. I am at a loss here, as I would expect it to be a BIOS issue, I would think. However not sure if updating or if there is an update to the Raid Option Rom that would correct the issue or not? I found an article somewhere on Intels site, somewhere (sorry), that stated something similar to the Raid Option Rom does not need to be updated because.... Maybe someone has some insight? Perhaps the same issue and you can tell me what solved it? Thanks a ton!
(update: 6/7/15 - updated to the last BIOS version from 12/22/2010 on Asus website. Have to mention their tech support, though I did get an email response from them, about a 0+ out of 5)... updated to the 2010 BIOS didn't change anything. thank you
Initial Intel RST Application view, after simply installing the 3TB drives. Keeping in mind I will have 2 RAID sets, Boot Raid (2TB drives) , Data Raid (3TB drives)
Update from shortly after posting: I decided to go into the Raid Configuration Utility during Boot up, since this is where you Configure the RAID sets so the OS (Windows 7-64 bit) can see them... As you see from the screen shot the Config Utility during POST shows 746.5GB, so I figured I would select them and configure my 2nd RAID set, just to see what would happen.
Here is after I selected the 3TB drives (ports 2 & 3) for my data RAID1 set. Again, you see 746.5GB, however each drive is 3TB.
Now here is what Windows 7 still sees nothing has changed. Since installing and prior to configuring the 3TB drives, Windows 7 and Intel RST Application has always seen the 3TB drives, as 3TB drives, period.. Now after configuring this 2nd RAID called 3TB, Windows still sees the drives individually and doesn't even recognize the 3TB RAID set..
INTEL RST Application (which I can NOT configure the RAID set inside this application for whatever reason, even if I run it as Admin), which I am the Admin anyhow.
