> you should also check fwdepot.com for information Yes, I just realized that this could also be related to the recent problems many folks have had with Firewire devices and Mac OS 10.3.6 and 10.3.7. Upgrading the Oxford bridge firmware on your enclosure may solve the problem. However, there is a serious mistake on the fwdepot.com web site. They state that there are no known problems with Oxford 911 chisets (Firewire 400) and Mac OS X, and that the only problems are with Oxford 922 chipsets (Firewire 800). That is a mistake. There are numerous verified reports that the problems are with both 911 and 922 chipsets, so ignore that particular comment you might see on some web sites. In any event, make sure you get the firmware update for the Oxford 911 bridge/chipset. Your enclosure is a Firewire 400 (Oxford 911) and not a Firewire 800 (Oxford 922). Art
