In workbench when you go to Hdtools and set the partition size,
i set the DH0 to 2GB, and then the HD1 i passed the 4GB limit and he passes from 4GB to 0 counting again, so imagine that i want 5GB, i set to 5GB but hdtool says 1GB that corresponds to 4GB + 1GB he passes the limit...
but after IDEfix installed he reads HD1 as 5gb but with SFS of course.
In FFS i think we can only go to 4GB, but i dont see why not 3 or more partitions of 4gb each... i must try it
