Pro Micro QCM1250, not recognizing second NVME in M2 slot

Question

Hi there.

Just bought an QCM1250 and plugged in 2x Corsair MP600 Elite NVMe Gen4 x4 M.2 SSD drives. I plugged them both but inside of the BIOS I only see one of them in the slot 0. I thought that maybe one of them is faulty so i swapped them but i also got the same result.

I also tried moving the drive that came with the server into the second M2 slot but the disk is not being recognized in the system.

Then I tried a Samsung 990 Evo Plus, and the BIOS also said that there is nothing plugged to that port.

I have updated the BIOS to the latest version (1.9.2) and nothing changed.

I also tried to start the install of Debian but the installer also can see only 1 disk in slot 0.

Is there any option that I should tick to enable that second M2 slot? In the BIOS storage menu they are both ticked to be active. I also read somewhere that the second M2 slot is GEN3 but I can´t find any information. Please, advice.

Regards.

I just got the PC back from the Dell service. The motherboard was replaced and now both drives are recognized, so it was a hardware issue with the PC.

I just got a QCM1250 and added a Samsung 990 + 1TB drive. Cloned the 256GB SSD that came with the box using Samsung Magician. Does OK, but had to disable the Boot manager as sometimes it would boot from the original 256GB, which is in slot 0, even though I removed the original drive from the boot selection. Maybe the boot manager overrides all that?

In the boot BIOS, removed the boot manager and told it to only boot from the Slot 1 with the 1TB drive. Hadn't wiped the original drive, so maybe it was getting confused on seeing two bootable drives with Win11 (yuck)? And then sometimes selected slot0??

Try change bios>sata operation from RAID (default) to AHCI

SATA/NVMe Operation Enable or disable the operating mode of the integrated SATA hard drive controller. By default, the RAID On option is enabled.

@redxps630​ Thanks. I tried that  but no luck. I also done a factory reset of the BIOS settings and the situation did not change, the second M2 disk is not being detected.

Any chance one of the M.2 slot is disabled?

M.2 PCIe SSD-0	Enable or disable the M.2 PCIe SSD-0 solid-state drive. By default, the ON option is enabled.
M.2 PCIe SSD-1	Enable or disable the M.2 PCIe SSD-1 solid-state drive. By default, the ON option is enabled.

@redxps630​ Both options are on. I even tried disabling them and enabling again, no luck. I ended up contacting Dell Support and they asked me to ship the PC to their center so they can look at it. Looks like a hardware fault. Once everything is finished, i will post the result here.

@user_372c3d​  Remember to remove the added 2x Corsair MP600 Elite NVMe Gen4 x4 M.2 SSD drives from the Pro Micro QCM1250. Those added Corsair SSD should NOT go back to Dell repair depot. Reinstall the shipped 256GB SSD that shipped from Dell. Then send it to Dell.

@DELL-ChrisM2​ Yes, thank you. Already prepared the PC to go as it came from the factory.

The specs are clearly saying 1x M.2 slot for wifi/bluetooth and 2x M.2 slots for NVME drives
