I've never used TechTool Pro to optimize (or defragment) my disk, but Norton actually moves data around on the disk to make all parts of a file contiguous. A word of caution: Norton updates the disk directory only when it has completed all moves, so if your computer crashes before it's done, the directory doesn't represent the actual ordering of data of your disk. Not good! DiskWarrior, which is what I always use, leaves the data alone and simply rebuilds the disk directory, thus accomplishing very quickly what other optimizers take far longer to do. Too, DW doesn't replace the old directory until you've had a chance to preview the new directory and compare it with the old one. If the directory is optimized, so is the rest of the disk.
