Absolutely - work around is a new FW enclosure.
If the 200GB is a Maxtor - depending on the HD model and what FireWire enclosure you have, you may be able to enable the special ATA/5 Maxtor Big Disk LBA support... but that is dependent on it being a compatible Maxtor drive and a FW enclosure with an Oxford 911 chipset and proper firmware updater support.
Otherwise, there is nothing to make the bridge in that enclosure support over 128GB.
