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?

Thanks Roberto.
