    Intel  Matrix Storage Manager option ROM v7.6.1.1001 ICH9R shows only 746.5 GB on 3 TB drives

      Hello!

       

      I just installed two Hitachi Ultrastar 7K3000 3 TB drives in my Dell OptiPlex 755.

       

      In Matrix Storage Manager option ROM they show up only with 746.5 GB each. Creating a RAID 1 volume is possible only with 746.5 GB size, but Windows 7 x64 completely ignores that (both Disk Management and RST iastorui V10.8.0.1003 report them as single drives).

       

      Is there any way creating a RAID 1 volume with 3 TB disks?

       

      If not:

      Using AHCI mode the drives show up correctly in Disk Management and I can create a software RAID 1 using Dynamic Disks.

      Is it safe or might the controller silently malfunction with these drives?

       

      Thank you!
