Unnecessary, and potentially hazardous, as it does, remotely, put your system at risk for serious directory corruption if something happens while it's running. Two reasons: OS X has a form of this built into the OS, as files are saved the system tries to keep them together. Disk IO is such that there's just not the kinds of noticeable lag there used to be. There are still a few times where defragging is warranted, but they're rare or specialized (such as video editing on a large scale), so that the preferred "Defrag" is backup, reformat, restore. For video projects you should really have an entire drive designated for your working one, and reformat it between projects. -- Bruce Johnson University of Arizona College of Pharmacy Information Technology Group Institutions do not have opinions, merely customs -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
