At work (tire factory) the carbon black in the air gets on the traces of the hard drives, reliability is a problem. One department tried spraying hard drives with conformal coating and greatly extended their life. The tech's from that department said it made a difference in hard drives lasting a couple of months to lasting years. Thought if some are having trouble with hard drive failure, conformal coating on the circuit board may be worth a try.
