Please do NOT use "Safely Remove" for flash drives. Just plug them in and
unplug them. If you used it with your Media Player, shut down the player
before removing.

Why would you try to "Safely Remove" your hard drive?

For most folks, "Safely Remove" has no practical use. It is mostly used with
devices that have delayed write enabled, and flash drives do not. The eject
function is fairly safe, but generally unnecessary as well. If you use it
with multi-card readers, it removes the reader, not the card.
