HI MY DEAR .HOW TO UNLOCK THE WD 750GB HARD DRIVE?

Here is a link with video instructions on unlocking and locking the WD Smartware drive. Keep in mind that if your password was forgotten there is no other way to access the drive unless you choose drive erase which will erase all existing data on the drive.
