Why are you trying to mount the firewire drive?
It's not necessary for dd to write to it. All you need to do is make sure
that the drive is recognized by the kernel and what it's node name (in the
/dev directory) is. dd will happily write to it without mounting it.
If you are just trying to copy certain partitions, you should have the
firewire drive already partitioned, though. A quick scan with fdisk on the
firewire drive will tell you for certain.
