Partitioning WD Advanced Format Drives in Linux
Raw
Using `parted`
--------------
Here's a transcript from formatting a WD20EARS drive on an x86\_64,
RHEL5.5, stock box. **Setting the unit format to sectors is bloody
important!**
[root@example ~]# parted /dev/sdb
GNU Parted 1.8.1

I haven't tried this but here's the command with flags that will align
the partition to 4K boundaries:
fdisk -H 224 -S 56 /dev/sdb
