The disk swap isn't the problem. The Seagate disk is failing (1176 bad sectors so far).

YA, that was one of my guesses. A bad Seagate drive. They just don't tend to last. Also when you pop in a new drive and the NAS has to do a rebuild, that puts extra stress on the other HDD(s). That tends to be the time a HDD is going to fail on you. Which is one reason why you should have a backup. At least the 3TB drives are reasonably priced. Though HDD prices arn't dropping down fast enough.
