Yes, u can us it at ntfs and change it to 64kb but u need to setp by setp increasing the cluster size, like 16kb->32kb first and than 32kb to 64kb..
u cannot change it from 16kb to 64kb at one time, it will show "not enought hdd space ...." error.
bsides, the home version is free but it cant use this function, u have to d/l professional version...
if u want the happy version, go search in google ~
