"I await Buffalo Technology’s firmware update to fix this"
Best of luck with that then! I have a Buffalo Technology encypted external drive that stopped working on my mac when snow leopard was released, I am also waiting for Buffalo Technology's firmware upgrade and have been for nearly 2 years, you may have to wait some considerable time.
