My copy hasn't arrived yet, but a couple of reports about problems with external drives over at MacInTouch are making me nervous, particularly considering that my initial install will probably be on an external FW drive. The gist of the reports are that on a manual reboot 10.3 will (or might) render an attached drive completely unreadable. That's not a forced reboot, just selecting "restart" from the menu with an external drive mounted via Firewire, whether it's the boot drive or not. There is one report from an apparent end user, and another from a guy who says the problems existed on and off throughout the development cycle. They don't give a lot of detail, but two is more than zero, and unnerving. Both of the two reports involve drives in a FW800 case, so I'm also wondering if it's limited to FW800 connections, or if FW400 and/or USB2 are also succeptable. Anybody had something like this happen, or is it more limited than it sounds?
