I'm just an interested observer at this stage - holding off a pcie SSD until the problem is identified, if not solved.I'm not at home right now to test, did you install the new update and see if it solves the original problem of this thread?

I had a Sonnet Silent M.2 4x4 with 4 Samsung 970 evo plus SSDs.Which OWC card? There are a few that I can think of as options: 1M2 pcie4, 4M2 pcie3, 8M2 pcie4
Also on which mac pro? 7.1 or 2023 14.8 ?
My opinion is that this has nothing to do with the Sonnet or NVMe drives. It's the way of how macOS manages the devices in PCIe slots, because if it was duo to mounting issues, there will be unmounted but present drive.
So here is my experience:
In slot 6 I have StarTech PCIe to NVMe U.2 adapter and connected to it is Micron 9300 Pro 3.84TB drive (Storage, APFS)

Last few days, on Sonoma 14.2.1 I had messeges like this, sometimes on cold boot, sometimes after restart:View attachment 2340138
After that message, there is no drive mounted or drive present as a device at all in the system
2 days ago, I have installed Sonoma 14.3 and problem disappeared. Let's see for how long.
Did you upgrade to Sonoma 17.3? Because yesterday evening I upgraded, but I had to go out, leaving MP switched on. Maybe it's a coincidence, but the SSD on the Sonnet card seems mounted without disconnecting. I'll try to test this evening for more hours.Mine hasn’t mount the drives twice already … so nothing fixed for me sadly…
Yes, just after the update to 14.3 it hasn't mounted the drives and once again switching back from windows.Did you upgrade to Sonoma 17.3?

You mean Sonoma 14.3 ? 😉Did you upgrade to Sonoma 17.3? Because yesterday evening I upgraded, but I had to go out, leaving MP switched on. Maybe it's a coincidence, but the SSD on the Sonnet card seems mounted without disconnecting. I'll try to test this evening for more hours.
these numbers make me crazy: ios 17.3, mbp 12.7.2, etcYou mean Sonoma 14.3 ? 😉

Disk Utility does not see the drives. I have been on the phone with Apple to reset the Recovery Mode password.^^^^Have you tried going into Disk Utility and mounting the disks from there?

Well the issue continues on my 2019 MacPro using 14.3.
This morning I had to boot, shutdown, boot again, shutdown again then reboot for a third time before all drives mounted.
Apple - fix this POS of an OS.
Which previous version of the OS does not have the issue?
Same here, I'm so disappointed.Just an update, it's been one week since I downgraded from Sonoma to Ventura 13.6.3. Since downgrading, I've not had a single issue with my 2 Sonnet 4x4 PCIe cards mounting and nothing has changed hardware or software wise, it's just Mac OS. Under Sonoma, it was random which NVME drives would mount.
You would think the most valuable company in the world would invest more testing into their main piece of software. Allowing such a singificant bug to slip through is laughable. I'm seriously considering never buying another Mac after the downtime this has caused me.
Our engineers have been working hard on this and have now been able to reproduce the issue. Just recently we were able to duplicate this issue with competitor's hardware. From the data we have gathered from yourself and other customers, it does seem that an update released by Apple in the 2023 time frame for multiple OS' caused the issue with drives dropping off. We are trying to narrow down exactly which ones. We are in the process of filing a bug report to Apple so that they can get the issue fixed in a future OS release.
Could it be a drive firmware thing?As a test, once the drives mounted I put my Mac Pro to sleep. After a while I woke it up and some drives were missing.
As stated earlier I have moved everything to a 4TB Samsung 990Pro that always mounts. This is a temporary workaround until things are fixed.
