Please allow me to phrase this question in a less contentious way, and a way which may yield more light than heat. After all, it is possible that the Apple technical note I referred to is wrong and that I am also mistaken. James - why do you believe that there is a performance improvement to defragmenting a disk drive under OS X? What have you observed or measured that leads you to believe this? I accept that this was useful in the days of OS 9, and wonder if you are thinking of that experience? What aspect of performance has improved for you, and by how much, and how did you measure it under OS X? Second, what is an "organization" improvement? I am not familiar with that term. Thanks, Peter
