I seem to recall reading that there are at least two methods of optimization/defragmentation. One method, as used by Norton, is to rewrite files as described above. The other, as used by DiskWarrior, is to rewrite and consolidate the file pointers. The later method, because it doesn't relocate the file segments, is much quicker to perform but leaves the files in a state which makes file recovery extremely "iffy" in the event of a disk problem. -- PCI-PowerMacs is sponsored by <http://lowendmac.com/> and...
