AFAIK fdisk does not support GPT partitioning & does not default to
correct alignment.

The stock disk tools in *buntu 12.04 are not up to the job either.
It is easy enough to build latest stable "gparted" from source on Ubuntu
12.04 & 10.04.

The "idle3-tools" let you increase the idle-head-park on the WD HDD
green drives.

My incorrectly aligned WD EARX 2TB green (ext4) ran about 30% slower.
