Although a bit late to this party (sorry...but I'm on vacation in the
Bahamas right now! It's
raining at the moment, which is the only reason I'm here) I think the most relevant bit is this, from the Apple KB:
QUOTE
Mac OS X systems use hundreds of thousands of small files, many of which are rarely accessed. Optimizing them can be a major effort for very little practical gain. There is also a chance that one of the files placed in the "hot band" for rapid reads during system startup might be moved during defragmentation, which would decrease performance.
I've never defragged a Mac hard drive since I started using OS X eleven years ago. I've very, very occasionally had to use DiskWarrior to repair directory errors - but at least half the time, that has been a fruitless exercise as the drive in question was actually dying a slow death.
Hey, have a super time and drink an islander drink for me. The rain will quit soon!
And not too much limbo.
