+ Arranges for the drive to be safely removed and powered
+ off. On the OS side this includes ensuring that no process
+ is using the drive, then requesting that in-flight buffers
+ and caches are committed to stable storage. The exact
+ steps for powering off the drive depends on the drive
+ itself and the interconnect used. For drives connected
+ through USB, the effect is that the USB device will be
+ deconfigured followed by disabling the upstream hub port
+ it is connected to.
+
+
+ Note that as some physical devices contain multiple drives
+ (for example 4-in-1 flash card reader USB devices)
+ powering off one drive may affect other drives. As such
+ there are not a lot of guarantees associated with
+ performing this action. Usually the effect is that the
+ drive disappears as if it was unplugged.
