Wondering if anyone can shine some light on this question of mine. I have a m-audio interface that im running with a 4-pin firewire connection. It says strictly that i should not hot plug bus powered firewire devices, but it also doesn't clearly state i can hot power 4 pin firewire. i would like to run in the interface any my external harddrive at the sametime, but only have one 4 pin firewire in on my laptop. any ideas? i don't want to throw the money on the usb cable for the hard drive...im broke
