Sorry I don't have the answer, but: https://wiki.archlinux.org/index.php/Advanced_Format shows the HDD WD20EFRX to be logical 512 and physical 4096 and http://excess.org/article/2010/11/wd-hdd-lying-about-4k-sectors/ It seems the first partition is aligned correctly. Hopefully the answer isn't "you have to calculate the sector alignment yourself and physically enter those values." -- The media's the most powerful entity on earth.
