Apple Event: May 7th at 7 am PT
I have an OWC minstack stx connected Thunderbolt 4 to a MacStudio M1 max and the 8 TB hard drive is not mounting The SSD mounts and operates normally. I've reinstalled Ventura and on the first boot the hard drive appears and operates normally but after a restart it dissappears again. very frustrating! It operated fine under Ventura 13.1. any hints? I can't figure out how to go back to 13.1 and Apple support says they don't support that
Hey Glenn,
I managed to solve this:
Everything is now good to go! Time wasted: 1.5 work days.

Happy to report that today's update Ventura 13.2.1 corrected the problem of my OWC hard drive not mounting. Everything appears to be working at first new boot up and shutdown/restart. Thank you Apple for listening to the end users!
I do not know what the cause might be for the failure to mount the drive. I have read many complaints about Ventura having difficulty managing external drives, though. Have you tried using Disk Utility to mount the drive? It would be a pain to need to do this every time, but I don't have another suggestion at this point. I have a Mac Mini that is still running Monterey because of concerns about this issue. It originally had difficulty mounting an external drive that I use daily. My solution was to set the drive as a Login item in System Settings. It's been fine since.
No. Setting the drive for startup on Login didn't resolve the issue. I deleted a couple of suspect Login items I thought might be causing problems (ie a toolkit installed from my Seagate Time machine drive which boots fine by the way.) the only wayI can get the OWC external drive to show is to either reinstall Ventura (then it shows only on the first startup) or unplug and replug it in. Once mounted I can access it with disk utility and all its contents are accessible. But on a restart, it doesn't boot up normally (or at all). The same connection boots the companion SSD without issue, very strange. Ventura 13.1 gave no trouble just after the upgrade to 13.2 the problem started
I just upgraded to 13.2, and no drive will mount to Thunderbolt ports except in Safe Mode. I can also work around with a USB-C to USB-3 adapter, which sucks and is slow.
The drives are all good, but none will mount or appear in Disk Utility.
Lucky you, I went through the same, but after two clean re-installs had to go back to 13.1 as 13.2 only worked for a little while, and then the same issue came back.
Time I provided free labour to Apple in troubleshooting and could not work on my stuff 4.4 days
Just to be sure Apple is aware so many are encountering this problem, it might be worth leaving feedback here: Feedback - macOS - Apple
The Drive doesn’t’ Show up in the disk utility but I’ll try your login idea
did you ever find out a solution for this?
I Hope Apple is listening I’ve received at least a half-dozen responses from folks having the same problem. Anyone find a easy solution let me know!
Thanks, buddy! Done.
Ventura 13.2.1 Update helps.
