--> I recall this being discussed and of the phenomena even having
    a descriptive name:  "sticktion".

    Once the drive gets past the 'stuck' point, it usually spins
    up to speed with no problem. The lubrication on the spindle
    tends to dry out, eventually, on older drives. The technique
    described above often solved the problem.
