Hello, Freebsd-hardware.

  WD HDD WD20EARS (Green 2Tb HDD) has "advanced" format -- 4Kb
sectors -- according to label.

  But output of it detection from ahci.ko and "camcontrol identify"
doesn't have any traces of it.

 Is here any way to be sure, that drive doesn't use internal emulation
with offset? No jumpers are set on it.
