Hey, y’all. I’ve been having an issue where none of my external drives mount when I plug them in. The Mount button in Disk Utility doesn’t do the trick, either. Importantly (I think), the drives do use FileVault. A couple things I’ve figured out:
  • It works fine for a while after I reboot the machine
  • Even after it stops working automatically, and stops working in Disk Utility, I can still do it manually by doing
    $ diskutil cs unlockVolume [UUID of volume]

It’s very annoying to have to go into a terminal and do this every time. Since it works after rebooting, there’s probably a process that needs to be restarted, but I have no idea what.

2015 13” MBP, 10.12.6 Sierra (yeah, yeah, I know. reasons. hoping to update the OS soon.)

Thanks!

Have you tried restarting Finder? I have to every now and then for some of my NAS connections.

Might be something in Launch Agents or Launch Daemons. Have a look in there (in both the user library and system library folders) and nuke anything suspicious and/or old.

I hadn’t tried restarting Finder, but just did, and it didn’t work. I have checked LaunchAgents / LaunchDaemons and nothing seemed amiss. Strange…. Thanks for the suggestions!

And this is happening on all the drives, and all USB ports?

Try a different cable.

Try a different port.

Try the drives on a different computer.

Try a hub.

Try the fifth dimension …

I was thinking you just need to buy a new computer, external drive and data connection.

Tried all that, including the fifth dimension. No luck, but thanks anyway!

Just curious, are these drives self powered or is there an external power adapter for them? Are the drives powering down when removed from the system?

I've only seen something similar when drives have begun to fail. When you have them mounted, what does the SMART status say in disk utils?

What is the manufacturer of the drive(s)?
