I don't understand what you and Loren are talking about. I see you using the word 'should' - making me think this is a guess? If anyone has opened up DiskWarrior or Norton on an OSX disk - they will see that after only an initial installation of OSX and some applications that Hard Drive fragmentation is quite apparent. Stuff gets thrown form here to there. After some months of use - the fragmentation is just as light or severe as OS9 had - all depends on usage. Or at least that is what is happening on my end.. Are these applications incorrectly reporting these results? I can see OSX being able to handle whatever is thrown at it.. But there are absolute performance differences on machines (HD's) that have been severely fragmented. On 12/20/02 10:29 AM, "Chris Olson" <chris at astcomm.net> wrote: > F.
