It draws power from the serial port. But which of the
3 pin ports on the drive itself to use, hmmm? Crack
the thing open and do some wire tracing from those
two 3 pin ports. Maybe they're just connected
together for daisy chaining power to a second drive.
I wouldn't try running more than one drive or other
power sucking device off the serial port though.
