Oxford has a new statement on their homepage about Panther Firewire issues: http://www.oxsemi.com/ "After extensive testing Oxford has identified that the issue related to data loss on FireWire drives under some Mac OS platforms occurs with OXUF922 based products with software revision 1.03 or less. It does not affect any other Oxford products such as the OXFW911 FireWire and OXFW912 Firewire800 bridge solutions. We recommend that end users upgrade to the latest version 1.05 software (released in September), available from the manufacturer of your external drive." In a nutshell, they seem to be saying that only FW800 drives with the 922 are affected. Since there are several posts on Apple's forums saying that people are having identical problems with 911-based cases (though these do seem to be considerably less common), I'd say that there is either a 2nd issue that has very similar symptoms, or some other Firewire issue in Panther that looks similar.
