    My friend was arguing that I should turn my MBP off before I take it to class or whatever because the hard drive could be damaged. I countered with the fact that the hard drive does not spin when lid is closed / the MBP is in sleep mode.

    He claims that the hard drive DOES spin when the computer is asleep.

    Who is correct?

    In sleep mode, the HDD is parked. In addition, if you have SMS (Sudden Motion Sensor) enabled, it'll prevent HDD damage from, well, sudden motion, like a rapid lifting or tilting of the machine.

    Tell your friend to quit taking cheap drugs.

    In sleep the hard drive is off. If you want to test for yourself, put your machine to sleep and the listen. It is completely silent.
