How to safely remove my passport device

I cannot “safely remove” the passport essential 3.0

When I right click to do this, ther is no option --only close the window or unpin from the taskbar.

Can anyone tell me what the problem is?

I have called WD and emailed and gotten no response.

I have already copied files successfully ( I think) and installed the software ( I think)

This is a known issue in some Operating Systems
