SATA Mode in the Windows 10 Reward $210
Created by marketsgolabl, 430 days ago, 803 views

I have a small problem on Acer Predator laptop PC on Windows 10.
I have an Intel HM170 motherboard with a 128GB SATA drive and a 1TB hard drive.

I have it for 2 weeks but something does not suit me and I would like to succeed in modifying that.

Let me explain :
When I go into Device Manager in the "Storage Controller" tab I have "Intel Chipset SATA RAID Controller"
The problem is that I want to switch to AHCI mode to optimize my SSD since I do not use RAID (since I have only one HDD)

The problem is that once the changes are made to the registry, I enter the bios of the pc and I do not have the tab "SATA MODE" which allows me to change the "RAID" to "AHCI" and I do not understand why ?

So I ask for your help. If somebody knows why,,

It is a laptop PC with the HM chipset ...
the BIOS configuration is rather limited and the configuration with the "RAID" controller is normal in reality.
It is the name of the Intel controller integrated in the chipset that supports the Raid but only activates it if configured .. not the case here, so you are already in AHCI.
SATA has only IDE or AHCI, we use more IDE and it has even disappeared from recent maps, so it is automatically xHCI

Hi @marketsgolabl

I agree with @chakramed and @ha14. But in most of the laptop PC will not support to SATA MODE AHCI while both SSD and HDD is connected; like in work-station or a personal server PCs. Either you have to use the HDD as bootable external hard-disk (if supported) or external network storage device.

If you have problem after removing HDD follow Enabling AHCI mode as told by @ha14 .

Kindly find Cristi72 reply in the below article:-

It is true till date for many laptops.
