MSI MPG x570 Gaming Plus Motherboard User Manual
Context
- System was built in April 2020 with only the Samsung Evo 970 M.2 drive installed (in M2_2 slot)
- System has been fully functional, running Windows 10 Pro, for 10 months
- Today (12 Feb 2021) I purchased and installed a new WD Black SN750 M.2 in the M2_1 slot
- The BIOS does not detect the WD M.2 in the M2_1 slot
- Testing revealed that neither M.2 is detected by the BIOS in the M2_1 slot
- The Windows 10 OS does not see the WD drive installed in the M2_1 slot after boot
Troubleshooting
Samsung 970 Evo M.2 in M2_1
WD Black SN750 M.2 in M2_2
BIOS sees WD in M2_2 but does not see Samsung in M2_1
Samsung 970 Evo M.2 in M2_2
WD Black SN750 M.2 in M2_1
BIOS sees Samsung in M2_2
but does not see WD in M2_1
Note that the WD M.2 isn’t shown in Device Manager
Conclusion
- System sees both Samsung & WD M.2 drives in M2_2
- System does not see either M.2 drive in M2_1
- Either the M2_1 slot is bad, or a configuration setting needs to be changed
- MSI – Please advise on next trouble-shooting steps
