AMD Ryzen 9 3900, ASUS X570-E, Vengeance 2x16 RAM
I have 2 SATA Samsung 870QVO SSD drives connected to motherboard SATA3 & SATA4 respectively, both with hot-swap disabled in the BIOS, drive letters S: & Z: I also have 1 SATA HDD connected to motherboard SATA1 with hot-swap enabled in the BIOS, drive letter B:
In Windows, I see drives S: & Z: as expected. When I insert the hot-swap drive B:, drives S: & Z: disappear. The only way to get them back is a reboot, sometimes I might even have to power off/on. My BIOS is 4002. In all other respects the 870QVO's work fine.
If I use 2 SATA HDDs in motherboard SATA3 and SATA4 instead of the Samsung 870QVO SSDs everything works as it should.
