I found out (a bit too late) that the WD 1 TB "black" drive that had come to me in sealed anti-static bag with a warning on it about "Advanced Format" drives (and possible OS incompatability) was not in fact itself an AF drive. Rather it is a traditional drive with 512 byte sectors. I tried doing a test install of FreeBSD 9.1-RC3 onto a different drive... one that I am quite sure had the new AF 4KB physical blocks and sure enough, all partitions were properly and automagically aligned on 4KB boundaries. I have put in a request to cancel the PR that I had filed regarding this issue. My thanks for Nathan Whitehorn for his input and forbearance.
