Perhaps you need the latest Macally firmware. A quick Google produced this page as perhaps being applicable: <http://www.macally.com/techsupport/drivers.html> Note the links to download firmware version 3.8 for Oxford FW911 drives. BTW, I have an OWC Firewire 400 80 gig drive and an ADS 30 gig FW 400 enclosure. Both mount appropriately under 10.3.6.
