M.2 with SATA SSD

[polloconadobo]

I am having trouble with a recent build. I have a b560m aorus elite motherboard with both m.2 slots using WD BLACK 500GB SN7100 NVMe Internal Gaming SSD Solid State Drive and SAMSUNG 990 PRO Heatsink SSD 4TB, NVMe M.2. Both detected fine but not the ssd connected to SATA. Are all SATA ports disabled while using both M.2 slots?

Some motherboards do behave that way, where certain pcie lanes disable certain sata ports, but shouldn't disable them all. Looks like you have 6. I bet some of them are functional, just try plugging it into different ports until one works. It might say in the manual. I did search for sata as a keyword with no luck but it might be in a picture or something, explaining exactly what disables which ports.

EDIT: Erm, wait here it is

According to this, looks like it only disables one....? And only if its a sata m.2...?

Well that doesn't make sense. Have you tried going to computer management to make sure its assigned a drive letter?
