So, I know that you ought to keep some of your hard drive clear to keep the computer running at top speed, and my 17" PB ain't got hd space or optimal speed by any means, at the moment. If I get space back, by deleting stuff, do I get that speed back? I'm thinking no, because the reason drives get problematic without free space is that they get fragmented beyond belief, and getting rid of pieces of data here and there isn't going to clean it up in that way. Not to mention, I've heard nothing good about defrag apps... anybody have any suggestions? Thanks. Now, I have to get a new drive, b/c I couldn't do with less than my current 40 gigs of music, now could I?
