I tried a new motherboard, new NVME drive, and csm support uefi legacy and both. Nothing works.
I also tried new pcie slots resetting bios.
I tried the onboard m. 2 slots and different expansion cards.
HDDS are detectable.
Have you tried an external NVMe to USB drive bay? Will help narrow down if the drives are bad or a firmware error/bug
Will also help if you list system specs and what model of the motherboards you tested with.
Ok I’ll get this going.
Using the NVME adapter they show up. The drives aren’t dead as I thought. What next?
E is the one thats connected via the adapter.
Hdds show up no problem only NVME drives are affected.
I wonder if (somehow) the physical nvme ports for those extra drives have failed. I assume your windows drive is using the fastest nvme slot (direct to CPU probably), the others would route through the chipset. But it’s difficult to imagine why.
By the way, I believe you’ll get quite bad performance from any storage media that is as fully loaded as your C and E drives are.
Well good news. Most, if not all, your drives should be fine. Two most likely possibilities are that you have bios setting/corrupted or the CPU/Motherboard has a hardware failure. Tbh based on your op it’s hard to narrow down…
First thing I would try is flashing the bios and updating all it’s firmware. I would also try updating the NVMe drives firmware with the USB adapter.
Since you’ve already replaced the motherboard that leads me to believe that the CPU could be damaged… I would try replacing that if it all possible. Could you post your system specs? Will help narrow it down and confirm prior to do this.

This depends on the CPU and motherboard. Per OP they already did a motherboard swap… So possible all of the drives route to the CPU making me think it’s the CPU, but hard to tell unless I see full system specs.

I tried using the physical ports all of them and also raid cards from PCIE. Currently using the PCIE cards.

99.99% sure threadripper uses the CPU for all it’s PCIe devices… So bad news is that you may have a faulty CPU. You could attempt to reseat the CPU, but considering you’ve already attempted a motherboard swamp my money is that something with the CPU has failed or an odd firmware bug has occurred.
If your CPU is in warranty you could attempt to go that route or at the very least work with AMD support. If not then you’re looking at replacing the CPU.

I made sure that my bios is in PCIE Raid Mode which I believe is x4x4x4x4 mode in this case. Then I tried a new processor and all my drives showed up. I tried my old processor again and issue was fixed. I believe I was too focused / tunnel vision to try PCIE Raid Mode. Since I was not using raid but 3 seperate drives. Either way.
Will look over a month to see if issue returns and keep new processor then or if issue is resolved.

Well glad to hear
Ah that makes some sense. I generally recommend avoid using hardware RAID on the motherboard, but some of them require it to be enabled to use more than one drive. Just do NOT use the motherboard to put your drives into a RAID array. It will fail and your data will be hosed. If you already have done this, I’d back up your drives and fully reformat them and rebuild the array within the OS.
Glad to hear that worked though!
In my experience with a good number of motherboards it is not actually hardware RAID, so much as it’s just a poorly labeled PCIE Bifurcation setting. Even my newer Threadripper Asus Sage Wifi A motherboard has the “PCIEX16 Bandwidth Bifurcation Configuration” with an x16 setting, the “PCIE RAID Mode” (which is just x4 x4 x4 x4 for x16 NVME cards that have no switching or logic on them) or an odd “GPU with x4 NVME SSD” setting.
I have settings elsewhere in the BIOS to enable hardware RAID, but the “RAID Mode” just let’s an x16 slot run x4 x4 x4 x4 Bifurcation so you can run up to 4 NVME per x16 slot.
