Comments/Problems:
Without leaving the blessed installation path it is impossible to
properly align the partitions for 4096 bytes/sec, e.g. for the
WD20EARS. This makes your Advanced Format disks _really_ slow.
Reference:

Expert mode was no help here. I had to reinstall, load parted.udeb
and switch to the console to manually define properly alligned
partitions.
Todays fdisk and parted don't have this alignment problem, so I
would strongly recommend to upgrade.
Regards
Harri
