Start with <http://docs.info.apple.com/article.html?artnum=302411>, <http://docs.info.apple.com/article.html?artnum=13628>, and the links they point to. There are only two things to do: 1) erase and reformat, thereby losing all the data resident on the partition or 2) use Norton's Disk Doctor, which I've found can fix these errors. Good luck.
