You are using "Scsi.device" in HDToolBox right? Is it seeing the drive? Once seen, setup partitions, with DH0: under 4GB and the rest as you please. Should work fine. You may have to unselect international mode, delete and reload FastFileSystem and try that. For some reason that made the partitions not seen until I unchecked it. Maybe that is a bug in the OS3.9 FFS, not sure, but try that.
