3TB RAID1 array problem

Last response: in Storage

January 28, 2012 10:46:56 AM

Building a new rig:
Asus P8Z68-V Pro/GEN3
i5-2500K
2 - 3TB Seagate Barracuda (SATA 6 - on Intel controller)
CM H80
16Mb Vengeance C9 (4x4)
EVGA 560 OC
CM TX650M

Followed the mob manual in setting up RAID in BIOS, then went to IRST utility as instructed. The screen displays accurate info as the RAID volume is None Defined and the Physical devices do indeed show the two 3TB drives. I hit enter to Create RAID Volume. I'm able to select RAID1 (mirror) option but when selected the Disks: item is grayed out and does not allow me to choose the disk to include. Same for RAID0, only Recovery level enables access to Disks:

What am I missing?

Verify if you can find a BIOS update for your motherboard. RAID with Intel controllers with 3TB HD are hit and miss because of GPT paritions.

You need a bios update that will support hard disk bigger then 2TB to be used in RAID mode.

According to the Asus support site, current BIOS is 0402 and that is what my BIOS is showing. Called tech support and they think it may be a bad utility - please let them be wrong as I can NOT afford to RMA this board. Build needs to go out next week.

HELP!

When you are in the RAID configuration utility, what version is it? You need 10.5 or higher to configure HD bigger then 2.2TB. If you have a lower version you need to get ASUS to update their BIOS

OK. I got the OK to go without RAID. I install W7 Home Pr and go to my computer to see what the system is registering and the hdd space only shows 2GB. WTF?

Is the Bios certified to handle more then 2tb drives?
Have you tried other ports/controler on the mainboard

I'm not sure if the BIOS is certified, although it is the latest per the mfg site. I can't imagine that I"m running into these issues due to the drive size.

I have not tried plugging them into the Marvell controller.

Go in the disk management, delete any paritions and make sure you use GPT and not MBR.

Yes your issues are because of 3TB drives. 2.2TB is where you run into limitations. To boot off a drive bigger then 2.2TB you need an EFI BIOS and to use more then a 2.2TB parition it needs to be GPT

In short... it's the system that is used to indicate how the HD is to be partition/formated. See it as the "index" and how files will be written and read from the HD

MBR is the "old" way and is limited to a partition of 2.2TB..

GPT is relatively new but can support partition in the Zetabytes or somewhere in that range

Edit: here is a link : http://en.wikipedia.org/wiki/GUID_Partition_Table

So can I just change in the Initialize Disk screen the radio button from MRB to GPT and that will not affect how I loaded windows, etc.?

Not following... you have 2 drives or more? The drive with Windows on it is already initialized...

What does the disk management console look like? Your C drive is what size? Can you post a screen capture of disk management?

Yeah this board doesnt support direct images... files needs to be uploaded somewhere and a link attached..

What does your drive with Windows on look like? a 2TB partition and some empty space and the end? Second drive should be totaly empty at this point

Yup.. this is normal for a Windows installation on a 3TB drive.

By default your installation used a MBR partition of 2TB and left the rest as unallocated. Naturally Disk 09 has nothing on it at the moment.

2 options:

1 - Allocate the remaining space as a D: drive of 700GB and the disk 09 as E: and use an GPT on this one for 3TB

2- Redo the whole thing and when you get to the disk selection of the installation, you will need to do some manual commands to create the GPT parition since the windows installation does NOT have the option to do it... You would then have a C: of 3TB and the a D: of 3TB

What do mean by "Redo the whole thing?" And what manual commands will I need to perform? Will they be easy to recognize? In the end. we I have a single partition on each drive (with the exception of the space for the System Reserved where OS is, that will show just under 3TB?

Sorry, being a new builder, as you can see, I need a little "hand holding"

THANKS!!

By redo the whole thing, I mean reinstall Windows by booting off the DVD and doing some manual steps when you get to the screen where you choose the disk that you will install to.

When you get to that screen press Shift-F10 and follow the following guide:

http://support.microsoft.com/kb/297800

Is it worth doing all of this? not sure unless you really need to have 2 paritions that are the same and that it is not acceptable to have

c: 2TB
d: 700GB
e: 3TB

Does it make any difference which controller on the mobo I plug these into - Intel or Marvell? Is one better than the other?

So I'm now at the point where I have to designate the volume of the remaining 746.52GB on Disk1 and I'm stuck. How do I get this last piece of unallocated disk space, allocated? What's confusing me is when I launch Intel RST (version 10.8 - latest off the Intel site), it indicates both drives are operating properly and have 2,861,xxx bytes available, so what am I missing. Device manager does not show the 764GB as available.

Assistance is very much appreciated.

The Unallocated piece only has Properties - all other options are "grayed out" and not accessible.
