Partition existing Partition with Terminal or Ubuntu

[mustangnc1]

I have an external Firewire hard drive that i would like to repartition into two pieces, one HFS+ and one FAT32. I have found products on the internet to do this like iPartition, but dont see a value in spending 30 bucks on it, i would maybe buy it if it were 10 dollars. Anyway, is there a way to repartition a disk through terminal or Ubuntu without losing data on the disc?

basic info:
i am running 10.4.5.
the disk i want to partition is non-system.
it is formatted HFS+ into a 55.9GB volume.
I want to split this volume in two, without losing data.

Any help?

If you search these forums (e.g. for "partition", or "repartition", etc) you will find some discussion of doing this (with the 'pdisk' command (if I recall correctly)).

But since none of these methods (commercial or otherwise) are without risk, you really need to have a backup of your data anyway. And if you have a backup you might just as well erase the disk and repartition that way.
