..

And one more:

$ hdparm -M0 /dev/sda

/dev/sda:
 setting acoustic management to 0
 acoustic      = 254 (128=quiet ... 254=fast)

$ hdparm -I /dev/sda | grep -i acoustic
        Recommended acoustic management value: 128, current value: 254
                Automatic Acoustic Management feature set

(the lack of a '*' on that last line indicates the feature is no longer enabled).
