Here are a few options.
1) Use a datatype with system_profiler:
`system_profiler SPFireWireDataType`, then grep what you need out.  
This is only available on 10.3 and higher, IIRC.

2) diskutil
If the name of the external drive will never change, or you only  
expect to have one drive attached at any given time, try using  
`diskutil list`. This will return a list of all drives and  
partitions, which you can also use grep on.

Hope this helps,
