I echo this.  As soon as a drive reports a *single* bad sector it should 
be replaced.  I've found that you get one sector, then two, then 5, then 
400.  You're already at the 5 stage...

Also, you seem to be obsessing over little things:  dust, filtering the 
air, etc.  Dust is going to do little to damage a drive.  However, keeping 
the drive relatively cool is incredibly important for reliability.  You 
sound like an end-user (rather than an administrator with a server-class 
box).  If so, make sure that your box has sufficient air flow.  Most 
consumer cases (even fancy "modder" cases) have way too little airflow, or 
have airflow in the wrong places.  You want lots of cool air being sucked 
in the front-bottom of the case, and lots of hot air being blown out the 
top-back.  Make sure that there is airflow over your drive(s) as well.

People put massive fans (or acitve refrigeration or water-cooling or...) 
on their CPU's and forget about cooling their drives.  I'd rather lose a 
CPU and motherboard than lose a drive.  I can buy new CPU's.  I can't buy 
new data!

And don't overclock.  But that's another conversation!  :)
