Firewire port in 2007 macbook vs. current macbook pro

[tigress666]

Ok, so my old, mid 2007 macbook had a firewire port that I plug my HD I use for time machine in (it can also be used as USB as well but I prefer it use firewire since I have uses for the two USB ports).

Anyways, this new Macbook Pro I have has one too. Except... the connection is smaller on my new Macbook Pro... So I'm guessing there are different connection sizes and I need a new firewire cable? I think my current cable has the same size that both connects to the hard drive as to my old macbook.

What labelling would I need to find to find a cable with the bigger connection on one side and the smaller connection on the other (Please don't tell me this means they are two different types of firewire or something and not compatible!!!).

the old firewire port was firewire 400. The new one is firewire 800. You simply need an adapter, or a firewire cable with a FW400 end and FW800 end.

The new one is FW800 and its faster, you just need an FW800 to FW400 cable and it will run your HD at FW400 speeds. You can connect more than one device to the port but if you have anything that is FW800 the whole chain will run at the speed of the slowest device.
