Frozwire is right!
My Book Essential have hardware encryption builded inside the sata/usb converter board, if this board is broken you need a new one (or repair the original one you have).
Are you sure that the sata/usb board is broken?
Do you see burned area, or smell of burned parts?
It's also possible that the Essential power supply is faulty.
There may be also a issue in the drive.
First i would check with MHDD if sectors are good, if so i will check firmware with Sediv.
