RAID controller has no driver, cannot access SDDs

Question

I'll preface this by stating that I am not very technically inclined, so I do not know all of the proper terminology, but I'll try my best to accurately describe my issue.

I bought a new PC about two weeks ago, and after some frustrations (a DoA PSU and UEFI/BIOS settings that were improperly configured by default), I got it to boot from the m.2 NVME drive as intended. To do so, I had to switch 'Intel Rapid Storage Technology' to OFF in the BIOS, enable 'Map SATA Controller under VMD', and disable 'Map PCIE Storage under VMD'. For the first week with these settings, I was able to access and use an old 125Gb SanDisk SSD normally, but I could not access my Western Digital Blue 2Tb SSD. In an attempt to access the larger drive, I switched RAID to ON. This automatically switched both of the VMD mapping settings to enabled. To test, I attempted to boot, and Windows failed to boot, citing an inability to access the boot device, which checks out. I restarted, fixed the VMD settings, but left RAID switched to ON. The PC booted normally, but is now unable to access either SSD.
In the BIOS, both SSDs are shown as being under the RAID Controller. Neither SSD appears in the Windows Disk Management, but the m.2 drive shows normally (I think). Western Digital offers a manager for their storage devices (including SanDisk), which detected the m.2 drive, but not the others. I know that Windows 10, the BIOS, mobo drivers, and m.2 drivers are all up to date. Device manager shows several warnings under 'Other devices' citing "The drivers for this device are not installed. There are no compatible drivers for this device." Among the affected devices are 'RAID Controller' and multiple instances of 'PCI Device'. Clicking 'Update Driver' yields "Windows could not find drivers for your device.". All parts are brand new, save for the SanDisk SSD.
It's quite frustrating being unable to access my main storage, especially considering that it was brand new and rather expensive. Since I'm not very knowledgeable on these things, I'm hesitant to mess with settings I don't know the purpose of and risk bricking my computer. I'm not even totally sure that this is the right forum to ask. Please help! I will include some pictures and specs to help y'all help me below.
Mobo: ASUS Prime B660 Plus D4
CPU: Intel Core i5-12400F
Storage: 1x WD Black SN770, m.2 NVME SSD, 500Gb (detected by Windows, BIOS)
1x WD Blue, SATA SSD, 2000Gb (not detected by Windows, detected by BIOS)
1x SanDisk, unknown model SATA SSD, 120Gb (previously detected by both, no longer detected by Windows.)

Answer 1

Hello, I'm Greg, here to help you with this.

Many critical controller chipset drivers are missing. You need to immediately install the motherboard chipset and all other drivers from the Asus Support Downloads webpage for your exact model: https://www.asus.com/support/Download-Center/

The SATA controller standard for WIndows 10 is AHCI, not RAID. RAID is for configuring hardware RAID arrays which you don't want as they are dated technology that loses files. Change the SATA controller to AHCI in UEFI Setup and if necessary install the AHCI storage driver.

You do not need to be out on a limb on this because new hardware comes with one year complete support, repair and replacement warranty under law. Asus Support should guide you to get the SATA issue sorted out, since Intel Rapid Storage can be a wild card that possibly needs to go. If you bought a builder's package then they need to provide the support.

So contact Asus Support next and then get back to me with what you find out. I'm an installation specialist who writes the tutorials for gold standard Clean Installs used by millions, so I can guide you on getting installed to that ultra fast NvME SSD once your drivers are in place and SATA sorted:

Answer 2

Installing the chipset and SATA drivers listed on the ASUS site you listed immediately fixed the issue. I had conflated the BIOS with the motherboard's drivers, and did not realize that the drivers needed further installation. Thank you for your help!

Answer 3

I am delighted to hear it.

Let me know if I can help further. I'll stay subscribed to this thread in case you need anything else, until the system locks it in a few months.
