SZ77R5
In a Windows 7 installation, how do I set up a RAID-1 configuration with two 3 TB hard drives?
Some of our XPC models such as SH67H3 and SZ77R5 have a problem when installing 3 TB hard drives in a RAID-1 configuration.
Windows will detect them as two 746 GB hard drives instead of a single 3 TB hard drive.
The problem is caused by an outdated Intel RST (Rapid Storage Technology) driver which controls the RAID function in our driver disks. Please download the latest RST driver from Intel’s website to a USB drive and load it during Windows 7 installation. After loading the updated driver, you will be able to see a single 3 TB hard drive.
