re-partitioning with Drive Setup

James Bond

I have a LaCie 60 GB drive, set up as 3* 20GB partitions.

I want to split one of the 20GB partitions into several smaller ones.

Silverlining (the partitioning s/w from LaCie) warns me that changing any of the partitions or adding more on the drive will cause *ALL* data on the drive to be lost.....presumably including the other partitions....which is not very friendly.

Drive Setup from the Mac OSX install CD looks like it might enable me to split the last partition without losing data on the others...but there seems to be no online help or documentation.

Does anyone know or have experience with this?
