Hi, I have an Apple Macbook from late 2006 that is running Leopard. My hard drive space has been disappearing for no apparent reason. I noticed the biggest jump this morning. Last night I had 9GB left on my Hard Drive. Now I have 3.7GB left. Can anyone explain why this is going on and/or how i could fix it? I restarted my computer and i now have 6GB left. But i want to know where that other 3GB went.
