Hello, I'm new here on the forum recently purchased the GA USB3 rev 870A. 3.1, but I am not able to activate the option eXtreme Hard Drive this mobo. According to my own this Gigabyte board features support this function, it has the SB850 south-bridge chipset. Even my BIOS is already updated with the latest version of the F4. XHD installed the program, but in time to perform the following message appears in a window: "Warning: No additional hard drive is available for migration!". After I click "ok" and the program does not open. My pc is running two 500GB WD drives in RAID0 and every BIOS is all set up and recognized normally. All controller drivers are also installed.
