Has anyone been able to get a 4tb drive working with the Extreme3 Gen3? I installed a brand new WD Red 4tb and it detects it only as 3tb, even in the BIOS. I'm running the latest 2.30 BIOS, and running in AHCI mode. I've also tried connecting the drive to the SATA2 and the SATA3 ports. No difference.

For the life of me I can't understand why it is not showing the full 4tb. I am certain this mobo supports 4tb. It's even listed as such on the ASRock ‘3TB+ Unlocker’ page – ASRock > 3TB+ Unlocker, which I've obviously tried installing.

It's also listed here as compatible with 4tb drives – https://au.pcpartpicker.com/parts/in...68extreme3gen3
