New PC build, SATA drives disappear on reboot...

Hopefully someone has seen this before....

Just built a new PC. Everything works great but when I reboot, two of the hard drives vanish. I have to shutdown and start for them to reappear. When they vanish, even bios doesn't see them. Drives are good, they're from my other PC, cables are good. Can't figure out if this is a motherboard hardware problem and I need to RMA it or if some setting is causing this... The two Vertex 3 SSD's are the ones vanishing....

Specs:
Motherboard: ASUS ROG Maximus IX Code
CPU: i7 7700k
RAM: G.Skill DDR4 4133 16GB (running at 3333 right now)
Drives: Boot: Samsung 960 pro 512gb m.2, Storage: Vertex 3 120gb x2 raid 0, WD Black 1TB x2 raid 0
GPU: EVGA Nvidia GTX 970
PSU: EVGA 1200 P2

Everything is watercooled with great temps.

Just to add some more info....

I moved the two vertex 3 drives to the same ports as the WD 1tb drives... The Vertex still vanished. So that tells me it's likely not a SATA port issue...

I then removed the Vertex drives and added two more WD 1b drives, they don't vanish, everything works just fine on reboots.

So I think it's some compatibility issue with the Vertex 3 drives and my Asus motherboard... Has anyone heard of this? Sure seems unlikely but I can't think of anything else it could be... I even changed power cables and plugged them into different plugs on the PSU... Only drives that do this are the Vertex. And they are just fine and work perfect until I do a restart....

Any ideas?

With out checking your mobo manual for myself......but I believe that your issue is with your SATA ports in the BIOS. Make sure that each port is enabled (turned on).

I found this out the hard way myself on my Gigabyte Z97 Gaming 7 mobo. Once I did that all was good.

Thanks, yeah, they're turned on... When I put the other pair of WD 1tb drives in their place everything worked fine...

Can't figure out why these are vanishing....

Are you sure? I literally had to turn my other 5 ports on (enabled them) in my BIOS.

I'm positive they are enabled. I have tested other drives in the same exact ports, in fact all of the ports. It sure seems like the board has a problem with Vertex 3 drives, and only on reboot, other than that they work fine.

Anyone else happen to have Vertex 3 drives on a Z270 board?

Hi,

Anyone else happen to have Vertex 3 drives on a Z270 board?

I had he exact same problem with a Vertex 2 (SATA II) drive. Not sure if there's a relation though.

Cheers,
