ASUS X99-E WS not detecting m.2 ssd

ebirckelbaw · Dec 15, 2015

Hello,
I built a computer with ASUS's X99-E WS board and all seems to be good except for some reason it doesn't detect the M.2 ssd.

I first tried installing the ssd into a different computer to see if it was faulty but it worked perfectly there so I'm guessing it must be something with the board.

After a bit of research I found that there was some bug that had issues with m.2 ssd's but as soon as I saw that I updated the BIOS to the latest revision (and supposedly the problem was patched many revisions ago) but still no cigar.

I have been exploring through the settings on the board to see if there's anything setting wise that would cause this. I couldn't find any other posts with this issue though, so I feel like this must be an issue with my rig in particular.

Any thoughts?

Thanks

-Eric

I'm assuming you mean the BIOS doesn't detect? and not just the OS?

Hi, What's the SSD model?

Barty1884 · Dec 15, 2015

Also, from what I'm seeing, you should be able to install your OS to it - regardless of whether the BIOS shows it as detected, provided you're in UEFI mode. Once the OS is installed, it should function correctly.

Yes, my apologies. The BIOS does not detect the ssd. I don't have an OS installed yet because I'm trying to put it on the ssd.

The ssd is a Samsung 850 evo 500gb - http://www.newegg.com/Product/Product.aspx?item=N82E16820147399

The windows installation wizard doesn't see it either - when you select the drive, it only lists my storage drive.

BIOS>Onboard Device Config>PCIe>Select M.2 ("Auto Mode" doesn't actually detect it)

ROG Video, but ASUS BIOS are similar https://www.youtube.com/watch?v=v7PEBscJbno

I'm afraid my BIOS doesn't have M.2 mode - only "Auto" and "x8 Mode" which I tried but didn't work either. The board says it supports M.2 devices...

Barty1884 · Dec 15, 2015

There's nothing else in there that has M.2 as an option? There are slight variances between ASUS and ROG BIOS - but not much.

From what I can see in the specs, M.2 is x4, not x8 so with the options available there, I would assume it's in another drop down. Do you have a screenshot? Specifically of the "Onboard Device Config" screen.

Barty1884 · Dec 15, 2015

The card is 2280, so should be supported. Simple step, but have you tried reseating it? There's reports of it taking more force than expected to fully seat correctly.

ebirckelbaw :

If I'm not wrong, and I think I'm not, that SSD is SATA. You need one that supports PCIe mode.
Something like http://www.newegg.com/Product/Product.aspx?Item=N82E16820104543&cm_re=m2_ssd_pcie-_-20-104-543-_-Product
If you check the manusl, it says that M2 is PCIe only.

ebirckelbaw · Dec 15, 2015

I tried reseating a couple times earlier and it's definitely all the way in - I doubt it'd be that but I can try again if we can't find another idea

I took a couple screenshots - how can I send them to you?

alexoiu · Dec 15, 2015

Check the post above. The SSD you have is not compatible with your board.

Barty1884 · Dec 15, 2015

alexoiu :

Oh. Ouch. alexoiu is right, you've got a SATA M.2 and a board that only supports PCIe M.2.

Samsung only released SATA M.2 as far as I know

Sorry!

ebirckelbaw · Dec 15, 2015

Crud - alright it's soon enough I can still return and get a new one that's compatible.

This should work right?

Barty1884 · Dec 15, 2015

ebirckelbaw :

Oh, guess I was wrong there. Yes, that's a PCIe based M.2 & 2280 so should be supported. Absolutely.

alexoiu · Dec 15, 2015

From board's specs: M Key, type 2260/2280 devices

ebirckelbaw · Dec 15, 2015

Okay thank you both for all the help!

alexoiu · Dec 15, 2015

No problem.

wildcard1978 · Jul 21, 2016

If the m.w drive ya night is nvme only support uefi so force uefi mode for storage or turn of csm legecy support and do full uefi boot if your other drives and video cards support uefi no reason to run legacy at all. Nvme ssds that have been releasing only support uefi means gpt partion only folks

Barty1884 · Jul 21, 2016

The board itself only supports SATA, not NVME Wildcard1978

wildcard1978 · Jul 21, 2016

Nope that's a m.2 gen 3 x4 slot on that board

wildcard1978 · Jul 21, 2016

His board should support that drive just fine

alexoiu · Jul 22, 2016

wildcard1978 :

What drive?

wildcard1978 · Jul 22, 2016

He said it was a samsung eco m.2 ssd hell that board hes got will even support nvme so shouldn't be a problem the 850 eco ain't even nvme I'm thinking his bios is hanging and not showing the drive on boot list needs to pull CMOS battery and clear CMOS newer boards can get finicky like that and hang and won't show drive on boot list with it saying uefi next to the drive for boot selection problly where he's having trouble
