OK, I have a strange problem that I can't quite work out. I have a gigabyte X570 Aorus Master, with 3x NVMe drives installed. They have been working fine for about a year in this config with no issues. However, last night I booted up my rig and 2 of them have disappeared from windows. Windows does not detect them at all, either in Device manager or Disk management. The strange thing is that they both appear absolutely fine in bios. They are different brands (one corsair, one samsung) so I don't believe they both could of died, which leads me to believe its either a Windows issue or a motherboard issue. I've reinstalled chipset driver to no avail, and tonight I'll pull the drives out and try to test them separately. Anyone got any ideas?
