Drive issues after macOS 13.2 update
I updated my Mac Studio to macOS Ventura 13.2 last night.
This morning neither of my external hard drives would show up in Disk Utility or in the Finder. The drives spun up and did not sleep. An SSD in the same enclosure as one of the drives always mounted normally.
I checked all 6 Thunderbolt ports, different Thunderbolt 4 cables, shut down and restarted several times. Etrecheck Pro found no problems.
Then I found this thread:
macOS Ventura reboot - Apple Community
and the helpful reply by P. Phillips, which reminded me of Safe Boot.
1 - Restart in Safe Mode. This will perform a Disk Repair, clear cache files and only load Apple Software, extensions and fonts. The boot up will be slow and can take some time - Normal.
2 - Safe Mode will also eliminate Third Party Software, extensions and drivers from loading
3 - Does the issue present in this mode ?
4 - Sometimes a Safe Boot followed by a Normal Boot will just put things right.
In Safe Mode, both external drives mounted normally. After a normal reboot, the two drives again mounted normally. So it seems that whatever disk repair the OS does during a safe boot fixed my problem.
