Try to dismount a USB external Western digital passport harddrive , it
will be ok but the cylinders will be still rotating , then if you unplug
your hardrrive it'll do a strange noise like a violent hard drive
parking. ( in Microsoft windows the eject the device safely option stop
the heads ) at the moment the only solution to stop properly the hard
drive is tu use sdparm , here is the script :

#!/bin/sh
WD=/dev/sdb1
sudo umount $WD
if [ $? -eq 0 ]
then
	echo Stopping heads
        #Stop properly the heads and cylinders
	sdparm --command=stop $WD 
else
	echo Unmount Failed !
fi
