x99 taichi NVME wont recognize

I can restart my computer with no issues. But after leaving my computer off over night the m.2 is no longer recognized. Not even in windows install. Anyone know the issue? And yes my bios is updated. EDIT: I just tried to find the drive by booting linux off my flash drive. still doesnt see the drive. I can see my sata ssd no problem. Anyone know of any solution?

By the NVMe SSD not being recognized, do you mean in the boot order?

Does your board's UEFI/BIOS have an NVMe Configuration screen, in the Advanced section? Also, in the Tools section of the UEFI, the System Browser feature, does that show the 960 EVO in the M.2 slot?

Have you tried clearing the UEFI/BIOS?

Which M.2 slot are you using?

What CPU are you using?

What version of Windows are you using? What did you use to install Windows, an optical disk? ISO file on a USB flash drive?

When you installed Windows, did you only have the 960 EVO connected to the board, or did you have any other drives connected to the board and running?

What was the entry in the boot order for the 960 EVO?

Did you install the Samsung NVMe driver?

I have two 960 EVOs that I use in a different ASRock board (Z270) and they have no problem as the OS drive, even when used in RAID 0.

I have heard of some bad 960 EVO released by Samsung. I use an Intel NVMe on my different ASRock X99 board as the OS drive, and it has worked fine for many months.

Hi arrowman, I had some similar experience with X99 Taichi so will detail it here in case it may help others.

Started off with RAID, some single SSD's and one RAID0 SSD. The RAID0 boot selection would usually replicate each boot until I had so many entries it wasn't possibly to enter the BIOS anymore.



Also experienced some unicode name corruption.



This happened with both BIOS versions P1.40 and P1.50, I didn't know what the heck was going on. There is also an issue with the boot menu where the mouse is unusable even though it works okay in the actual BIOS setup pages. Looks like the mouse pointer isn't updated on screen but that's a different issue.

To restore the boot menu I wiped all BIOS boot variables and order using the shell bcfg command which cleaned things and decided to get rid of the RAID0 and use a NVMe instead.

Bought W10 which came with some cheap looking USB flash drive instead of the usual DVDROM. That USB flash had both 32-bit and 64-bit versions but didn't play well with the X99 so copied just the relevant 64-bit section onto another FAT32 formatted flash and all was good. Installed W10 with GPT and CSM with no problem. Multiple restarts okay but when shut down and later cold booted the NVMe did not show up in the BIOS.



Long story short I ended up with these settings

CSM enabled, UEFI storage driver, Video legacy, fast boot disabled.




S_SATA3 controller(s) disabled.




And touch wood never had a hiccup since with Plextor M8PeG NVMe wise although runs a bit hot for my liking. Might fabricate a better H/S sometime. Menu appears to show both MBR and GPT for the NVMe but just using GPT.

Understand.

Out of curiosity did you try F11 while BIOS was posting to see if there were some corruption as shown in the previous post when the missing NVMe occurred? Just wondering if it happens with a BIOS save settings op.

So no response from @ASRock_TSD in 3 weeks and no BIOS update for the last 5 months, can I take it this issue is not going to be looked at, ever?

Thanks for the input Parsec.

BIOS P1.40 is a backup BIOS and original with board, P1.50 was tried to see if it would help (both exhibit the problem).

Tried removing OCZ drives and when re-connecting Vertex 3 which is very similar to Agility 3 and I do see corruption so you may be on to something there. Normally I would find that hard to believe but given OCZ's past I'm not surprised so much. Will try to do some more testing later on.

Cheers.

Also FWIW the NVMe disappears from BIOS seemingly as a result of this corruption.
