However, you also would have seen that, in addition to the MacFixIt article (posted to the Web just this month) that I quoted in my previous post in this thread, other folks with a huge amount of first hand knowledge and experience have found that defragmentation is necessary as your drive approaches 80% full. (At least it is if you want to avoid directory damage and flaky behavior from your Mac.) e.g. MicroMat, Intech, etc. Or, you could just get yourself another drive before your drive reaches the 80% full mark.
