The meaning of "safe to remove device" for external USB drives is that any
data written to the drive has truly finished being written, the cache has
been flushed and no data lose will take place when you unplug the drive.
If you are certain that writing to the drive is finished, then it is
probably safe to unplug the drive, after at least once using the safely
remove device utility.
Logging off, by my experience, should be sufficient to flush the cache and
allowing you to "safely" remove the drive.
Sometimes I log off and log back on and the safe to remove drive now works.
I would not bother to reboot the computer, unless I had some very special
important data that I could no take any risk whatsoever that I might lose it
and I don't have it backed up anywhere else.
