I don't think he's talking about hdparm here; he's talking about the
fact that different sections of the disk have different performance
characteristics.  Try it as a secondary drive with the OS on another and
split your drive up into, say, 1GB partitions and run Bonnie++ or
another disk performance tool on each of them.  With 120GB, you'd
probably want to script it for sanity :)
