Okay, well let's say that defrag is a Windows
problem then. Defragging programs for Mac or Linux do exist, but they are near useless, because if you have fragmentation on your HFS+ or ext2/3 drive, it means it's close to being full. Because of the way those filesystems work, they only fragment files when absolutely necessary, which makes the results of defragging them unnoticeable. Defragging ext2/3 or HFS+ could arguably actually hurt performance in several ways. It's best to just let those filesystems do their job, haha. For a quick primer, check out this:
