I just received my 2TB My Book Studio Pro II  and installed the software. I opened the WD Manager and told it configure the two 1TB drives to a RAID 1 (mirrored). In the middle of that process I connected a second external HDD (that contained my iTunes, etc). The mounting icon for my 2nd HDD appeared, then disappeared briefly, and reappeared, renamed and EMPTY! YIKES. I ejected, reconnected.  No change.  Still renamed, still empty. Restarted.  No change.  Still renamed, still empty. Any suggestions? ---

Try a data recover software. Disk Warrior is powerful but is not free.
