How large is your HD and how much availble space does it have? If it's full then you need to remove or move files to an external HD. The most common item to use lots of hard disk space is media such as music (iTunes library), photographs (iPhoto and/or Aperture) and movies. If you have large libraries of one or more of these then get an EHD and move the libraries to the EHD.
