It does look like your storage controller got switched to raid mode. Some ai generated slop-fix:
Your storage controller actually is visible in the lspci output, but it is currently hidden inside a RAID cluster.
Look closely at this specific line from your list:
00:17.0 RAID bus controller: Intel Corporation Comet Lake PCH-H RAID
Why Your Drive Seems Missing
- Intel RST Active: Your motherboard BIOS is configured to use Intel Rapid Storage Technology (RST) RAID mode.
- Controller Hiding: When RAID mode is active, the Intel controller intercepts individual NVMe or SATA drives.
- Linux Limitation: The standard Linux kernel cannot see individual NVMe drives behind this specific Intel RAID controller without configuration.
How to Fix It
You need to switch your storage controller from RAID mode to AHCI/NVMe mode.
- Reboot your laptop and enter the BIOS setup (usually by pressing
F2,F12, orDelat startup). - Locate the Storage Configuration, SATA Mode, or VMD Setup menu.
- Change the setting from RAID or Intel RST to AHCI (or disable VMD).
- Save and exit. [1]
