New WD External Drive Can't Eject & Files Won't Display on MacOS I cannot see the files or folders on this external hard drive and I am unable to eject the drive. I must not lose this footage.

The drive is a brand new WD My Passport 25E1 Media 2TB External Hard Drive. I'm using it to store large amounts of video footage. It's only a few days old. I've had no problem transferring and opening files on the hard drive until now.

When I first purchased the drive I formatted it for MacOS using Disk Utility. It is currently a Mac OS Extended (Journaled) partition. It has never been plugged in to any other Mac or PC.

Current Problem

The hard drive is plugged in to my iMac. 


When I view it in Finder non of the hundreds of gigs of footage display. No files, no folders.
I cannot eject the drive. If I attempt to eject the drive I get this message:



  The disk "My Passport" wasn't ejected because one or more programs may be using it. I have not tried to Force Eject.


There is valuable footage on this drive I cannot lose. If I view the drive in Disk Utility it shows 318.15 GBs used and 1.68 TB free. This indicates the files are on the drive but not visible.

Steps I've Done So Far


Attempted to Eject the Drive
Confirmed Storage is Used in Disk Utility
Closed All Open Applications &amp; Attempted to Eject the Drive
Logged Out of my MacOS User Account &amp; Attempted to Eject the Drive
Opened WD Drive Utilities and Clicked "Run Drive Status Check" and "Run Quick Drive Test" with No Effect, Results, or Message. It doesn't do anything.


Right now I'm seeking guidance because this footage is essential and cannot be lost.


How do I confirm the files are still on the drive?
Why does the drive not display the files or folders it should?
Why can I not eject the drive?
Should I attempt a "Force Eject", and if I do, do I risk
losing the files on the drive?
How do I identify what programs are
running that are preventing the drive from ejecting?
How can I eject the drive?


Help in this matter is immensely appreciated.
Restart your Mac

At the risk of stating the obvious (as you didn't say you've tried this), have you fully shutdown your Mac and then rebooted to see if the drive appears and functions okay then? 

Use a different port

Shutdown your Mac and try connecting the drive to another port. What happens?

Safe Mode

If restarting your Mac and trying a different port makes no difference, can you restart your Mac in Safe Mode and let us know how that goes?

Follow these steps boot your Mac into Safe Mode:


Fully shut down your Mac
Restart your Mac
Immediately press the Shift key and keep it down 
Let go of the Shift key when you see the login window (NOTE: If you have FileVault enabled you may need to log in twice).
Take a note of what happens (i.e. could you boot your Mac okay, is the issue still present, etc)
To exit Safe Mode just restart your Mac as normal


Once you've booted into Safe Mode, let me know how you went and we'll go from there.

BACKUP

Finally, you really should have a backup of your data. You've made it pretty clear you have valuable footage on this drive you can't risk losing, so you really should have a second drive for backup purposes.
