WD Black 4 TB in BIOS as a secondary drive


I’m going to change the drives in my PC into a larger configuration and I want to know if I will be able to do this.

My motherboard is a Gigabyte GA-EP43-DS3 (supports SATA2 and Intel Core2 Quad), uses a “normal” BIOS (not UEFI) and supports AHCI.

I’m going to set a 500 GB SSD as the boot drive (it works even it’s SATA3, I’ve tested it) and I want to add a new 4TB WD Black drive as a secondary drive. Theorically, the SATA standard supports large drives.

This is my problem: some sites say the disk will not be recognized at all (bad news). Others, the disk will be recognized only if it’s not the boot drive (good news). Others, the disk will be recognized without a problem (perfect news).

My MB manual doesn’t say anything about this. Will it work? Do I need to enable AHCI?

My OS is Windows 10 Pro.


The SSD should work without a problem as well as the 4TB drive.

Thank you. I’ve ordered it today. Hope it’ll work.

Today I’ve received it… and it works!

Thank you again.
