Thunderbolt 4 nvme drive issue on M1 Studio w/ Ventura 13.4

Hi all. Apologies in advance for the book.


I've had an M1 Mac Studio since the end of last year. I use it for Audio Production. I have been reliably using an NVME drive (APFS format) in a TB4 enclosure as my main audio drive since I bought it. It never gets removed (or even touched). All of the sudden about 3 days ago, the drive just disappeared from my machine. I did all the normal things - unplug/replug, try a new TB port, reboot, etc... It wouldn't show up - not in Finder, Disk Utility, or in the terminal. So I unplugged it and tried it in my Windows machine. Disk Manager saw all of the partitions. I was able to mount and browse them using an APFS driver. All of my data was there. I wiped the drive. I plugged it into my other Mac (an M1 Mini) and was able to format/mount it just fine in there. I also ran First Aid on it and it didn't find anything. I then took it back to my Studio - nothing. Same as before. I bought a new TB cable (a certified TB4 cable from OWC) and had the same results.


Fast forward to today. On a hunch, I take my Dell Thunderbolt 3 doc (that I use with my Linux laptop). I plugged it into one of the back TB4 ports on the Studio and then plugged the NVME enclosure into the TB3 port on the back of the Dell Dock. BOOM... It shows up on the Mac. So I unplug the enclosure from the dock and plug it directly into the Studio again... Nothing.


I'm convinced this is a software issue somewhere dealing with the Mac Studio hardware. I don't think it's a general Ventura issue because my Mini has the exact same OS rev and works fine. I have yet to reach out to Apple Support.


The only thing I haven't done yet is to buy a different enclosure and to try that, but I'd rather not if possible, since the TB4 ones aren't the cheapest.


Does this sound familiar to anyone?


Note - the NVME enclosure I am using is this one - a Bus powered one. https://www.amazon.com/gp/product/B0BB5W3QGQ/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

Interesting. I had the same issue on my Mac Studio. I was using a WD NVME drive in a TB enclosure (Acacis). All was fine until one day stopped working. I moved it to my other Mac (Intel) and worked fine. I then reformatted the drive and used another brand of enclosure (Trebleet) and it started to work on the Studio. Then I put the drive back into the original Acacis enclosure and tested again and it was working once again. Have not been able to figure out the issue. I'm using Monterey.

Not sure this applies, but since we are talking about drives that won't mount:


We occasionally see drives fail when they were not ERASEd when new, but the maker's Utilities, including Paragon or Tuxiera NTFS Drivers were installed. All proceeds fine until that Driver is not included in the MacOS image being used, then the drive 'mysteriously' stops working.


A drive set up by the maker as Windows New Technology File System (NTFS) can have MacOS Volumes created on it, either MacOS extended or APFS, when those Utilities are present. But when the Utilities are not there (a different Mac, a different MacOS, or something else) the drive won't mount. But It will show up in Disk Utility.

yea that totally makes sense. Until I started this troubleshooting, this particular nvme drive had never been attached to a Windows machine before and it had arrived unpartitioned and completely blank, so I knew that wasn't supposed to be an issue. Also, as part of the troubleshooting, I did completely wipe and destroy all of the partitions on the drive before re-initializing in my Mac Mini with a single APFS partition. In all steps of the process this week though, I could not see it in disk utility at all on the Studio.

The cabling is fine - I tested with the original TB4 cable the enclosure it came with and about a new TB4 certified cable this week. it's the same behavior on both. The enclosure is bus powered (no external psu). I will also stress again that this exact enclosure with this exact drive worked absolutely flawlessly in this Mac for 6 months. Literally the only thing that has changed in recent memory are standard system updates.


This is what the TB4 device tree looks like on the Mac Studio - Notice it says nothing is connected to any of the ports (even though all 4 ports are populated).



And here is the Mac Mini (where it shows up just fine with the same cable). The one I highlighted is the drive/bus in question.

I've never heard of that Konyead brand before. I'm always leery of unknown brands especially on Amazon. I like to stick with well known established brands especially for anything important.


I do notice the Konyead enclosure mentions it is a dual protocol enclosure and switches automatically as needed between Thunderbolt & USB protocols. I'm guessing it is this auto-switching which may be causing problems for the OP even if it is showing up as Thunderbolt 3. It would be a point of concern for me since it is impossible for the user to choose the protocol desired. Maybe this explains why the dock/hub allows it to work.

Did you ever find an answer for this? I'm having something similar happening.


I just bought my first NVME with a USB enclosure for my M1 studio, and the NVME fried in 3 days. Computer store said the drive was totally dead. Swapped it and the shell out for a different brand drive and shell. The current one is still working after a week, but the first night I used it, I cam back to find it had unmounted mid-data transfer. So now I'm pretty hesitant to use it as my main working drive. (of course I have backups)


I had found some threads talking about USB 3 enclosures for NVME and Mac studios, so I thought that was the issue. Until I found this! I haven't had any issues with my 2.5" SSD's yet, but I also found a thread about the M1 messing up two of those in a single week!
