It really is a visually fascinating thing to watch, Joe -- at least as Norton Utilities used to do it. You saw a real-time visual representation of the scattered bits of data being gathered up from various parts of the drive, held in readiness until space was cleared for them in their proper areas, and then deposited there. The various types of files -- system files, documents, applications, fonts and so on, were represented in different colours, so it was easy to follow. If Techtool Pro, which Karl is talking about, does something more or less similar, it's well worth seeing; way more fun than a lava lamp ;-) It might well make a useful part of next meeting, if there's time, and if someone (Karl, perhaps?) has a copy. I'm certainly going to get one, but likely not in time for September. I've just had to replace my roof, and am in the process of replacing some windows, which has rather blown the budget for a while. If I'm still solvent after that, the first software priority is a CS3 upgrade, and then probably will come the defragger. Meanwhile, I've Improved the iBook's performance at least somewhat with Disk Utility and by manually clearing out a lot of old documents and the last of the System 9 apps. Do you, or does anyone, by the way, know if there's any reason not to scrap the entire OS 9 System Folder? anything in there that OS X actually requires, if it's not going to be required to run anything in Classic mode?
