SSD Misteriously appearing and disappearing on GA-Z97X-UD3H

[danidemi]

Hi, I've just bought and assembled a PC with a GA-Z97X-UD3H mobo and an M.2 ssd from Crucial.
I'm experiencing a very strange situation.

When I boot the PC, I cannot see the M.2 ssd drive from within the bios. Crucial says to repeatedly disconnect the m.2 ssd from the mobo, wait 30 secs, reattach it. If I do that, magically, the ssd appears again.

But then.... night come and I usually turn off the PC during the night. Next day, same story... the SSD disappears again.

All the rest of the system works perfectly.

Any idea ?

Both mobo and ssd are up to date to latest firmware.

I had a corsair doing the same thing I RMA'ed it and they sent me a new one and it worked perfect. I would start with the ssd and go from there.

i had this same problem but it was because i was still using BIOS and not UEFI.

I could boot the machine, pick the boot drive (M.2) and it would boot Windows.
But if i left it alone (boot priority M.2 drive) it would give me the "non system disk" error.

deleted the MBR partition on the M.2,  created a UEFI USB windows installer, re-installed and now all is good.

prior to this the drive would frequently disappear from inside the BIOS.

Pretty impressive performance.

I had the same problem with a pair of them but I fix it with a firmware update. If you turn off the power with the switch on the power supply.

You should be able turn it back on and see you SSD again. That is how I did it till they came out with the firmware update.

Plus I was using UEFI too. So  CCraMM you just got lucky that it work. It is the SSD that is the problem. There has been a lot of people that have the problem.

So danidemi if you want to try what did CCraMM did. Just go in and set you first boot to UEFI DVD-rom you have that option.
