I'm not sure when this started, maybe when I setup my Time Machine partition to be encrypted or maybe at a particular OS update, but the Time Machine drive no longer ejects properly. I'd love some help on this one!
Here's what happens:
I have an external drive with two partitions: an encrypted partition for Time Machine, and another AFPS (Encrypted) one called "Extras". The drive plugs directly into my MacBook Pro 2015 15" running macOS 10.14.4
On a fresh restart with the drive plugged into a USB port, the two partitions appear normally in both Finder and Disk Utility. Time Machine works and everything is good.
If I eject the drive (either from Finder or Disk Utility), it appears to eject normally (disappearing from Finder, greying out in Disk Utility) until I actually pull the USB cable out of the MacBook. Instead of the greyed-out drive disappearing altogether from Disk Utility, nothing changes.
If I plug the drive back in, then the Extras drive appears again in Finder but Time Machine does not. In Disk Utility, it looks a little weird (see below): a second drive appears with the same name (but nothing under it), and the Extras drive appears under the initial drive.
After plugging hard drive back in:
I've tried various combinations of
eject with the
diskutil command, and once in a while a command sequence does work… but it's never repeatable. Now I just have to restart the computer whenever I want to access Time Machine again.
Any ideas here? Thanks for reading.
