Just curious on how everything worked out for you.
I am in the midst of a similar problem as described by you in the OP. My Safepoint backups completes with errors ever since I upgraded the firmware.
I referenced your post to WD Support and they report the contrary–no known hardware / software issues related to the latest firmware. In the same message, they did provide me with their RMA link to have the unit replaced.
I am wondering if you replaced your unit and if you did, were you able to get Safepoint to work correctly again? If so, what firmware version are you running?
