What happened both times was the system would not shut down properly, in essence it froze. I shut down using the power button (ImacG5). It then wouldn't boot up. Using Disk Utility from a System Disk, it was diagnosed both times as "invalid B Tree Node Size" and not repairable. TechTool couldn't fix it either. The second time I had obtained a compatible Disk Warrior boot disk. It went through 5 hours of repair to a new directory. Using the new directory, it wouldn't boot up. In both cases I eventually rebuilt a Retrospect catalog which predated the problems and restored from it. Although everything is working properly, I'm just a little wary that whatever caused the problem(s) might still be there.
