Just putting out some feelers here but the question goes like this, how is the performance of a hard drive affected once the hard drive's capacity exceeds 50%? I saw in a post dated Aug 04 about it, some said it was bunk and others said that there may be something to it. I feel from my observations is "seems" to be true. As in why is a new install of an OS so much better than one that is a few years old, i.e. HDD is filled up with stuff.
