Perhaps the free software from Seagate helps - text from the Seagate PDF below:
Newer versions of Windows (Windows Vista and Windows 7), when combined with a new BIOS called UEFI and when configured correctly, have the native capability of using hard drives larger than 2.1TB. The problem, however, is that UEFI BIOS systems are less prevalent and more expensive than legacy PC
BIOS systems. Also, Windows XP systems still represent a sizable portion of
the installed base. So what do you do if you want to use one of the new
high-capacity hard drives coming to market that exceeds this 2.1TB limit?
Seagate has the answer.
Seagate has broken the 2.1TB barrier by developing a creative solution which allows you to utilize all of your hard drive capacity over two or more partitions when the drive is larger than 2.1TB. The new Seagate® Barracuda® XT 3TB hard drive has been released, and it includes free access to our updated Seagate DiscWizard™ software. This newest version of the popular hard drive utility from Seagate now includes functionality that allows you to easily configure a virtual device driver to access all of your hard drive capacity.1 It’s simple, fast and free.
That's what's weird. It IS a new motherboard with UEFI, the HDDs are brand-new, and I've tried Windows 7 (among others), but the problem is still there. I really expected more from Intel. Thanks for the suggestion Stubi, my drives are indeed Seagate. If there is no way to fix this properly in the MB, I'll give it a try. Otherwise I just inherited some very expensive paperweights.
I trying to use two new WD 3TB in our S1200BTL Server. BIOS recognized those HDD, but the Intel soft to configure the RAID mode, and also the Windows 2008 R2 intaller, won't recognize them as 3TB HDD.
I try upgrading the BIOS with this file:
Version: 41;1.17;1.16 (Latest)
Size: 32.57 MB
Operating Systems: OS Independent
but there is no change. Can you help me, please?
What is the RAID option that you are using? The ESRT2 controller does offer support for larger drives but it does not support GPT installation.
For this purpose, I would recommend using the RST RAID option instead and follow the instructions for “Plan B” from our White Paper to perform a GPT installation.
