No Drives Appearing w/ Dual M.2 Adapter

Hey everyone, I purchased a Dual M.2 Adapter second-hand and separately a brand new GPU Interposer. When I plug in some drives from old but functioning computers, none of them are recognized by the laptop. I’ll tried plugging them in individually as well but no luck. The fans are running though with no issue. BIOS has been updated to 3.05. Any ideas of what I could try next?

The M.2 adapter only supports NVMe SSDs, the top SSD you inserted is an older SSD Samsung PM851, a SATA device, so probably not compatible.

The lower SSD says NVMe on the label and should work, though.

Which operatign system are you using? Have you checked a device or partition manager if there is maybe a device error or something?

I think you did not connect the Framework interposer - or am I wrong. I don’t see it in this picture.
And in that case, the nvme adapter is electrically not connected to your board.

Not exact .. the Framework adapter does some bifurcation. If one thing doesnt like PCIe then its possible that both of them won’t show up

Took me a few tries as well, but that SATA SSD in there clearly doesnt help. In my case I was testing with Optane, which is PCIe. But PCIe 3 x2, not x4.

Curiously the Optane straight up work in none of the slot. Including the main board 2280. Which is bad.

The GPU interposer have a sequence of installation. If you dont do it right you can mess it up. I messed up one of the plastic peg already. But fortunately the thing still works.

Screw in the main board side first (the one connected by the mini-bridge). Then the m.2 adapter side.

The GPU interposer isn’t pictured here cause this was the only way I could take a picture of the adapter with the drives visible. I do the screws connecting the expansion unit to the chassis (the ones to the left and right of the interposer unit) then I screw in main board side first of the interposer followed by the m.2 adapter side. I assume that because the fans work that the interposer is installed correctly.

I figured the SATA SSD might cause trouble so I’ve tried installing only the NVMe drive, SATA SSD removed, but also no luck. I haven’t tried installing the NVMe drive into the mainboard to see if it could be recognized so maybe that’s the next step.

That is a good next step. But just to make sure, do the drives show up in BIOS?

Update: put the nvme drive in the top slot, reinstalled the interposer and it worked! I don’t think that it’s a top vs bottom slot thing. Maybe there was something off with the interposer when I installed it and after re-seating and screwing it back in it worked?
