Z390 Carbon MB, 32 Gb memory, 750 Watt Pwr Supply, MSI 1660 TI VIDEO Card.
Both hard drives are good.
EZ Led boot light is on all the time.

Isolated to SATA 1 only. Still does not see the hard drive. ?????
New to MSI. Don't see any reference to the Hard Drive Controller in the BIOS.

Added on 8-5-2020
Bought and installed new M2 - Samsung 970 EVO Plus and installed Win 10.
M2-1 is PCIE and the three drives are connected to SATA 1, 2, and 3. Should be okay.
Z390 MB works fine but still cannot access the 2 Hard Drives and the DVD that are installed.

Please help.................

Sounds like a bios bug, did you update the bios and report the bug to msi?

Thanks for the reply.

I did update the Bios but that did not help.

I didn't report it to MSI. Bought new M2 drive that works fine.
I think the drives were MBR and there is a problem with old MBR drives.
New drives (UEFI) seem to work fine. But, I don't know for sure. Just a guess.

Interesting, not sure that's exactly what's going on but glad you got something worked out anyway.
