I have the same drive and the same problem. This is a partial duplicate of https://bugs.launchpad.net/ubuntu/+source/gnome-disk-utility/+bug/802153 since misalignment is likely a result of the starting sector incorrectly set by palimpsest. I'm not an expert on this, though, and bug #802153 doesn't bring up the MBR vs. GUID aspect, so I hesitate to mark this officially as a duplicate. Would be nice to get some progress on this though, since it was reported over 1 year ago and 3TB drives w/ Advanced Format are becoming more common for better or worse.
