I purchased the 980 Pro at that time. The problem started because the firmware on those drives was faulty, causing them to fail randomly later. I checked the situation further—if DiskPart can't recognize the drive, that's a major concern. You might want to try connecting the second drive and see if it appears in DiskPart. If it's an M2 drive, swapping it out could help determine if the issue lies with the motherboard.
Thanks for sharing your experience. It sounds like you've worked through several troubleshooting steps and finally found a solution. Your persistence paid off, and the clean installation was a big relief after two months without a PC. Let me know if you need any more help!
Checked if the Intel storage drivers were available on your mainboard vendor support page. At the disk selection screen, tried loading a driver when no disks were visible, and selected it so it could be saved to a convenient location on the installation media.
RST stands for RAID mode. The name seems confusing. I'm glad it's resolved. Please tag this as a solution for future reference.
