I was copying files to a firewire drive and noticed that the copying process was stuck at the same point for a couple hours.
I couldn't shut Camino down, despite using Force Quit. I tried all the classic key combo's but no luck. So I used the power button.
The Mac restarted just fine. Then I got a bright idea (famous last words): Disk Warrior the system drive.
I put the DW disk in, restarted, pressed "C" and got the spinning circle (not the beach ball) under the apple logo forever. When I released "c" the Mac rebooted from the system drive, not the DW disk.
Here's my really bad move: I reset Prefs to start from the DW disk. It will do that. It takes awhile, but DW comes up. So I checked the system drive, and tried to reset Prefs to start from the system drive. But Prefs was shaded out. That's when I made a panic post to this forum, but I found a page that told me I could press "option" and choose the startup drive.
But I still wonder: should it really take forever (never) to hold "c" down to get the Mac to start up from whatever is in the CD tray? Or should I just use "option" since that came up almost immediately?
One caveat: I have a KVM switch, and just before using the "option" key I connected the keyboard directly to the Mac -- wonder whether that could have made a difference.
