Help needed for m.2 ssd boot issue.

[innovade]

Hi,
I have a pc witb Asus ROG H370F mother board with window 10 installed. I have 2 M.2 Samsung 970 evo installed as well one of then being my boot drive.

Today i tried to switch on my pc i was brought to the BIOS page immediately. I tried to select boot page and strangely my boot drive is all gone and not able to detect anything.

I tried meddling with the setting but it not working. Any solution on this please help.

Try removing the 2nd 970 and ensure your bootdrive is the UEFI 970? make sure u set the other boot drives to disable

Depending on your CPU, motherboard and the amount of CPU lanes, the feature such as Hyper M.2 in the UEFI BIOS might be turned off. Thus, no drives detected. Though by right, one drive should at least be detected. Worst comes to worst, try removing the other drive and just leaving the boot drive. See if it can be detected. If not, use the other M.2 slot on your motherboard. Check the manual if you have to allow for PCIe Hyper M.2 to be turned on as well.

Maximum M.2 drives that I can use on my Core i9-9900K and Z390 Asus ROG motherboard is just 5. 2 on the motherboard itself and 3 on the Hyper m.2 PCIe Gen4 card. But on an X8 PCIe slot it can only detect 2 M.2 on the card. So I will have to sacrifice my GPU to the X8 slot and put the Hyper M.2 card on the X16 slot in order for it to be able to detect 3 m.2 drives on the card. But thankfully, not much loss for putting the GPU on the X8 slot due to the rendering bandwidth being below the X8 bandwidth limit.


Anyway, you can try checking for any BIOS updates as well. It's weird that your mobo just out of nowhere lost your M.2 drives in them. Try a longer reboot. In other words, a complete shut down to make sure there is total power loss to the mobo. And boot it up again in about 10 minutes.

happens if you dont shutdown properly

just use windows setup and see if the drive still there, some lousy bios cannot detect

Hi,

Thanks for the response was busy thus my late response. I have tried doing a long restart and it didnt work. Will only be able to detect when i turned on CSM setting in BIOS if not it will not be able to detect both the SSD.

@it_geek can check how to enable raid 0 configuration???

@yusoffb01 didnt do a improper shut down

Tried updating BIOS no luck too...

I had the same issue with you awhile back. It had something to do with the bios. Something along legacy mode or UEFI. Sorry i cannot recall exactly what it was.

I once had my oldest SSD that I had with me since 2013 died 2 years back. When it dies, it will just disappear. Like as if I do not have a drive there. Unlike mechanical drives that gives you signs of it dying with extremely slower speeds. Thus you can go out, get a new drive and quickly (more like painfully slowly) transfer as much files off that drive prior to it dying. But for SSDs, when it's gone, trying to load it internally or with a USB enclosure will show nothing.

So what you can also do is go out and buy an M.2 NVMe enclosure like the Asus Strix Arion M.2 enclosure (but make sure it is compatible with the type of M.2 that you have in your system) and try to see if maybe your other laptop/PC can detect that drive. If have, then we can rule out the drive being the problem and it must surely be your motherboard misconfiguration and whatnot.

Have you tried resetting your BIOS/UEFI as well? It might help too.

Else, if you are willing, can send to the famous person, Nigel, at Sim Lim Square level 2 to help you troubleshoot. And you can pay him any amount. He's well known here in HWZ for being super helpful and you can charge him any price that's fair.

hmmm after much tinkering i can only get my pc to detect my M.2 SSD by enabling CSM setting in the bios. I cant seem to find any other alternative solution to this..sigh i guess i have no choice but to continue using my pc via this setting.
