Doubtful. According to Adam, it doesn't always happen. My take is that  
the extra power demand of the optical drive is more than the PAV can  
handle, and everything shuts down. I've not ever seen a hard drive do  
what you suggest. But I've seen power demands by peripherals cause an  
iffy power supply to shut down a complete system.
