I just checked my laptop, it say the Vista "C" is 28.5 GB free of 74.2GB. The sounds is not all the time, but mostly I hear the sound when I am trying to open some web pages. I am confused. How could this laptop be easily filled up with data where in I don't often used it. Do I need some kinda separate hard drive to store some info. This I guess start to come out when I recently donwloaded couple of clips from the web. Pls. help.
