incidently, anyone know where (in the UK) i can get a bus powered Firewire enclosure for the old 40 GB Hard drive, I can only seem to find USB2 ones and as the powerbook only has USB1 I'd rather avoid using USB.
Firewire laptop drive caddies are not easy to find but this looks fine

even located in the UK which is even more unusual and £15 delivered seems a reasonable price - its USB and Firewire and even comes with a 6 pin to 6 pin firewire cable so should be bus powered though you might want to check that with them ! Some caddies need the USB cable connected to provide the power to the drive - but not always. The listing seems a bit vague on whether it is powered through the firewire connection but since it is 6 pin then it probably is.
