hey guys. just a theory. how feesable would it be to power a 3.5" usb hard drive from a firewire port on say a laptop? I understand it puts out 30 volts but I'm not sure. would you need to use a voltage regulator to drop it down to 12v for the hard drive? I understand that laptops may not be able to supply the full 30 volts and if it can, can it support such a task? I only ask for the possibility of using a large drive in a mobile environment.
