Updated iMac Pro to Sonoma 14.0 - I had 4 external SSD drives that are now refusing to mount. They are each on separate USB cables and there is no way all 4 became simultaneously corrupted. Disk utility reports com.apple.DiskManagement.disenter error 49229
They are encrypted, however. What am I missing?
Mac Pro (2019)
I have reported a similar bug, whereby my Sony A7R4 camera does not mount two of the three in-camera folders. It mounts PMHOME but not untitled and untitled1 where the actual photo files are stored. Annoying.
Similar situation, with WD drives, unencrypted. 4 separate drives, 2 different cables, nothing mounts. I've let the drives sit connected (drive power light is on) for over 2 hours, and it never mounts.
I had this problem too. Tried everything, but nothing worked. Then Googled for macOS updates for Sonoma... and found 14.1.2, installed it, and everything is back to normal!!!
I don't know why the Apple techs wouldn't have suggested that already on this thread.
Now 14.1.2 did NOT show up as an auto-update option or notification on my computer, despite the fact that I was running 14.0. I had to search for it. And it took hours to download which suggests that it is being rolled out to a lot of people, perhaps on a rolling basis.
I spent some time on the phone with a senior support manager, and we concluded it was a "feature" that would be rectified in the next update. Waiting is...
Unable to mount any external drive - error 49229
