HDD Bad Sectors question...

It happened like 3 months ago I had to shut down (via force shutdown i.e. holding the power button for over 3 seconds) my Mac after the system became un responsive during an empty trash operation. Then while running apple software update Windows (running Windows via bootcamp) it also locked up (it like completely froze no mouse movement at all). I would like to know if that created a bad sector in my HDD by doing this forced shutdown procedure. I reinstalled Mac OS X just to avoid any problems down the road after the forced shutdown.

Again the question is: Does a forced shutdown can create a bad hard drive sector?

Also, is there a way to recover bad HDD sectors? Disk Utility perhaps?

Thank You for your time.
