My Passport for Mac 1TB USB 3.0 won't eject from OSX

Hiya, please help.

My Passport has been working and ejecting fine for the past 6 months - no problems. Then, I started my PhD and discovered that all my data has to be password protected.

So, I set up the password protect on my excellent functioning My Passport and felt safe…until I tried to eject it.

It won’t eject (it gives me the option to ‘Force Eject’ which doesn’t look good) and says there is a program still using it but I can’t find one. All programs are quit.

I shut down the computer, restart, unlock the My Passport and am able to eject safely with no problems. So what is the problem?

I don’t want to have to do shut down my computer and wait for it to reboot this EVERY time I back up (every day).

Please can anyone help.

Many thanks

Hello,

It is possible there is a program /software / application that’s is trying or is accessing your drive when you re trying to eject it. 

Make sure this is not the case.
