..
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).
