MB is X9SRA-F. We are installing 2x Seagate ST2000NX0243 2TB 2.5" Drives on the X9SCA-F Board with BIOS 2.1 We are enabling the Intel RAID.The issue we are seeing is that with these 2TB Drives connected up the Intel RAID BIOS doesn't come up. Which means we are unable to configure as RAID1 Mirror.
The drive is 4Kn type that is not supported by Intel RSTe and LSI RAID firmware. 4Kn drive is only supported with SAS2 and SAS3 controlle with new firmware update, and in UEFI mode.
