The desire to "DE-FRAGMENT" an OS/X'd Hard Drive, as one would an OS/9, is to be STRONGLY AVOIDED!

Bad advice, IMO. While 10.2 and .3 do some of its own on-the-fly disk optimizations of smaller files, it easily allows HDs with large files to become BADLY fragmented - which greatly reduces their performance.


I'm not one to advocate defragging often. But when you deal with large files, it can be necessary.

With any extra disk space, you can copy files from one disk or volume to another. That, in effect, defragments them. Safer than Norton, I think. And if you want to fix any bad blocks, you can reformat your drive(s) beforehand.

Good idea, except most of my 120GB disks are almost full, but I suppose buying one more "maintenance" disk would solve that...

IMO, the best scheme is:

Put the OS and apps on one volume, that you just leave alone. It will be mainly smaller files, so let OS X manage it.

Put your big work files, videos etc, on a different volume or (better) a totally different HD. Defrag that by depending on OS X's adaptive clustering plus copy/backup-erase-restore or a 3rd party defragger now and then.

Check out this Apple article for more detail. Even Apple recommends using a 3rd party defragger (see the end of the tech article)!
