M.2 Compatibilty

[rariza]

Hi, I have a HP Pavilion All-in-One - 24-r104la, with a M.2 SATA slot on the motherboard. I have bought a SATA M.2 disk, I installed, but it was unsuccessfully detected by the BIOS.  I have updated my BIOS and tried different settings without successful detection. Now, the manual says the M.2 is a SATA conector, but it can be that the connection is for a NVMe/PCie M.2 Disk?

@rariza,

If you look at this link, you will take note that the offered M.2 is an SATA variant.

Further proof it is a SATA III NAND m.2 port

Hi,

That is strange.

HP usually does M.2 PCIe NVME on consumer PCs.

The M.2 socket would have two open notches. One on each side if it supports SATA and/or NVME (Key B and Key M).

The motherboard OEM decides what protocols  to support.

Thanks Wb2001, 

Just to be completly clear, the disk I have is a WD GREEN M.2 SATA.  Only a SATA III with NAND will work?

Hi,

If you go into Windows Disk Management is the drive visible? If you try to install Windows 10 with bootable pendrive, is the M2 drive visible?

You could also try flipping the drive and see if it works.

The WD green should work in the machine.

Hope it helps,

David

Hi,

Nope. Is not visible on windows in any way, not even with pendrive.  Flipping is not possible. I checked the disk in another PC and  it works fine.

Hi Rariza,

I trust Wb2001, Iomare is also very sharp.

Plus Crucial is showing M.2 SATA support.

Can you send an image of your MB's  M.2 socket pinout (Link to various M.2 pin configs)? Scroll down this site to see the M.2 pinout diagrams.

It is very unusual to see M.2 SATA support on HP consumer PCs.

HP Enterprise PCs support SATA and PCIe on the M.2 slot. Some business PCs (older) only support M.2 SATA.

This is very perplexing!

Have you tried a PCIe NVME part such as a Samsung 970 on the motherboard?

A key M M.2 socket has the sixth pin removed on the right side of the socket. This pinout supports PCIe NVME drives.

I´m looking for a -borrowed- PCIe disk. I´ll let you guys know if it's detected and that solves the issue.

Hi Rariza,

Sounds good.

But can you send an image of the M.2 socket so we can see if it is a combo key B and key M or key B only or key M only?

This image will tell a thousand words. The only remaining question would be what protocol HP is using if it is a combo socket.

Found no borrowed PCI SSD so far. But finally some photos for you guys.
