Just did a SL 6.0 install on a machine with two Hitachi 2TB drives with
4K sectors. parted warned me that the default values I'd chosen
weren't optimal for the sector size and I adjusted manually.
Note that I set these drives up post-install -- no idea if Anaconda
would have done the "right thing" or not.
