Loss Data of my external WD MyBook Studio Edition II (RAID 1) after upgrading ! PLEASE HELP ME!

Hello,

after upgrading from OS X Mountain Lion to OS X Mavericks my external HDD “WD MyBook Studio Edition II” configured as RAID 1 with two 3 TB disks “WD30EFRX” connected with FireWire 800 was empty and renamed to “MyBook” → ALL MY DATA ARE GONE 

I lost all my photos and movies of my family and my kids from the last 20 years !!! 

Are there any chances to get the data back?
