Hey Normco,
First of all, you should still see your picture in the video monitor as you log, no matter if preview in the L&C window is disabled or not, so it would be a “good thing” to work with a video monitor (a TV set if you don’t have the dough) connected in your FCP setup. Many people do not, and really should.
Second, if you have a deck/camcorder and a FireWire drive daisy chained, you are subject to this happening to you again – so if you don’t separate the two devices to separate buses via a PCI card or PCMCIA card – you’ll have to continually trash prefs when this happens again. This doesn’t happen on my system, I’m assuming, because my devices are on separate buses.
