My Passport Ultra I ran latest update now can't eject

[chiclet]

I have Passport Ultra I Tb purchased in June 2014. I updated to version 2.4.6 and now when I try to eject I get a message “This device is currently in use. Close any using device and then try again” . I have closed dropbox and onedrive and don’t have anything else running. Any suggestions ?

Thanks

Do you have any automatic backup software running?

I have Dropbox and one drive but I closed those and It still wouldn’t eject.
