content: I had the same trouble too. A 2 or 3 TB WD drive that the NAS board died in. I did some research and found that using mdadm with a USB linux boot key, I was able to copy the data safely off the drive and reformat it to something that was more useful. Sure hope it is something that simple for you OP and not some new funky hardware encryption. In any case that was my last time ever buying one of their setups, though their drives are great if you stick them into your own NAS or computer.
