Just to be sure, did you mean grep acoustic (lowercase)? Because it is listed there under Capabilities: Recommended acoustic management value: 128, current value: 0
I've tried with the 5 sata drives I could get my hands on, they all list some recommended acoustic management value but all fail the same way
# hdparm -M 128 /dev/sda
/dev/sda: setting acoustic management to 128 HDIO_DRIVE_CMD:ACOUSTIC failed: Input/output error acoustic = not supported

I have hdparm v8.9 here, is that new enough?
Thanks for you help, Soeren
