wormser: yeh, I don't know what was wrong with me that day I wrote it - some wires got crossed it my mind or something

Of course I meant the outer tracks, just reverse what I said before.
SteveJL: I have tested this extensively, partitioned drives perform about 10% worse in any case I've tested right from the get go, and as the partitions get more cluttered it gets steadily worse. All the advanced defragmentaion ulitities I've tried also warn against partitioning your drive if performance is an important factor, unless you partition it to bard off the low performance area, which some people do - but I don't find that nessesary, I just make sure my drive is always at least 40% free and dynamically defrag it once in a while.
