If you want to actually SEE your HD being "bad", meaning proving to yourself beyond a doubt that it's bad, run HDD Regenerator. You can see it failing to repair sector after sector. Eventually you'll become a believer.
However, it will probably run your HD to the point that any data recovery will be impossible. If you care about the data on the HD, get it recovered first, then worry about the HD itself.
