I'm running Snow Leopard and have found some bad sectors on my hard drive. Looks like I'm in need of a fix here.

How do I go about fixing these bad sectors? Is there a program or tool that I can use to fix this?

Fix bad blocks on Mac hard disk (2010-06-02) and note that in some cases, the user may wish to recover data before auto-relocation – writing data to the drive will most likely result in volume or data corruption if a bad block is found and spared. –  Graham Perrin Apr 1 '13 at 18:41

If you hard drive truly has a bad sector, then try Tech Tool Pro v5. But if you have bad sectors, it typically is a unrepairable issue. Bad sectors should be transparently mapped out using spare sectors on the hard drive.

If you are seeing it at the user level, then your hard drive is dying. Back up your data, and purchase a new hard drive.
