You need RST OROM 10.5 or later to support physical disks >= 2TB. Check with your motherboard manufacturer for a BIOS update if your RST OROM is lower than 10.5. Also, it's not supported on controllers older than ICH9.

I have a DP67BG motherboard with the 2040 BIOS on it, where would I get the new RST OROM, is it part of the BIOS update?  Where do I look to find out the current version?  When I tried to build Windows 7 x64 with UEFI and RAID enabled, the OS only saw a 746GB drive.  I had to change it to AHCI to see the full 2794GB, which prevents me from using RAID on any of the other drives in the system since there isn't a seperate controller for the SATA III and SATA II ports.  I have currently only purchased 1 because of all the issues I have heard of people having with getting these larger drives to work but I'd love to be able to have a mirror of my 3TB of information. My HDD is a Seagate Barracuda XT ST33000651AS 3TB 7200 RPM 64MB Cache SATA 6.0Gb/s hooked up to the internal SATA port 0.

Thanks.

Yes the RST OpROM is part of BIOS update. You can check the version in the BIOS release notes.

hello

I have found this thread a little bit late and created a discussion  'How to create RAID with Intel Rapid Storage Technology 10.6.0.1002 on ICH9R with 3TB disks' before, but I don't understand all requirements to use a RAID with 3TB disks, so please can you give me the answers?

• Do I need a bios version which supports a RAID with 3TB disks even if I only need a software RAID with the IRS 10.6.0.1002?
• Do I need a special chipset version?
• If I see all my 3TB disks (with full capacitiy ~2,7 TB ) inside IRS 10.6.0.1002, how can I create a RAID? (there exists no button to do this)

thanks

To answer your questions:

• Do I need a bios version which supports a RAID with 3TB disks even if I only need a software RAID with the IRS 10.6.0.1002?
  • Yes the RST OROM needs to be 10.5 or later
• Do I need a special chipset version?
  • Requires ICH9R/DO or later
• If I see all my 3TB disks (with full capacitiy ~2,7 TB ) inside IRS 10.6.0.1002, how can I create a RAID? (there exists no button to do this)
  • Follow the RST User Guide

thanks Edward

but the user guide couldn't help me to get my answer for my last question.

Now I have put 2 older disks (1TB each) into the pc and 'voila' I have got the create button. That's what I was looking for. The button visibility depends on the hardware. With my 6 x 3 TB disks I havn't got it. 

Hi Edward,

Just resurrect an old answer...

I've got a DQ35JO board with an ICH9D0 which I would like to recognise drives >2TB.

The latest BIOS update for this board (1143)  doesn't take the RST OpROM past 10.5.

Is there a way to do this 'manually' please?

Thanks

Matt

Very unlikely. And the board has been EOL'd for two years, so there won't be any new BIOS release for it.
