This was the point of my bug report.

I had written to a drive that I couldn't see the LED on.  When the icon 
disappeared from the desktop, I thought the drive was safe to remove. 
Guess what, it wasn't.  Ouch corrupted drive.  Repeated many times.

The proposed changes will be more in line with Windows that you will get 
a pop-up saying that it is safe to remove the drive.
