My Book Essential 2TB USB3/USB2 Disk Unknown Unallocated

My Book Essential 2TB USB3/USB2 is in a very strange state… It  can not be initialized and it is unallocated in Win 7. I’ve tried to view it on a XP, a MAC and on tried vigorously to view any of the data using TEST DISK. I believe it may be stuck in an encrypted state. Can any one help. I’m a wedding film maker and there is some important data I’d like to be able to retrieve. I should also mention that it was formated for a MAC BOOK PRO MAC OS EXT KERNEL JOURNALED.

Thank you in advance for any assistance in this matter.
