Question Changing SATA mode from RAID to AHCI

[edward.vasilache]

Hello,

I have a system with an M.2 SSD and an HDD.
I have Windows 11 installed on the M.2 SSD.
The HDD is empty and I would like to use it for simple data storage (no RAID).

The issue is that I don't see the HDD in Windows (including in Disk Management).
I do see some references to it in BIOS (screenshots) and it worked just fine when I connected it to another PC.
I tried enabling CSM but that didn't change anything.

I noticed the SATA mode is set to RAID and I'm wondering if I could safely change it to AHCI (without losing any data from the SSD) and if that would help me see the HDD in Windows.

Motherboard: ASUS ROG Strix X570-E
CPU: AMD Ryzen 9 5900X
SSD: 1TB Corsair Force MP600
HDD: 2TB Seagate BarraCuda Compute

Thanks!

If the drive is empty, I can't see why your mainboard's BIOS would have had any default settings pertaining to RAID use anyway, and even if it had been used as such, I don't think simply changing a BIOS setting would truly affect anything on the actual drive at that point anyway, even if it had data. (It would make the RAID functionality broken, of course, if it had been utilized)

In short...change away,

We certainly will need the drive to show up in Disk Mngmt before you can initialize and quick format it...

Before you play with this you want a complete backup of anything you do want to lose.

Go here and look at #2.
