parted and fdisk, parted was I think mentioned in what you snipped, but
fdisk doesn't know how to even check alignment. (that I know of) The
last time I used fdisk I got write rates under 15 megs/second on a
sata-ii interface. I backed it up and fixed it with gparted and its now
doing about 120 megs/second.
Secondary question. On efi setups, how much blank space in front of the
1st partition is needed for that stuff on a terrabyte drive? Or is
there even a rule of thumb about that?
