Dear all,

why is acoustic management via hdparm not supported for sata disks?

# hdparm -M /dev/sda

/dev/sda:
acoustic = not supported

No, that means that your *drive* doesn't support it.
Check for yourself, with "hdparm -I /dev/sda | grep Acoustic".

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


Aren't they Seagate drives? They're known not to support acoustic management.

..

Is there any patch flying around that already enables this or even any
ETA in the current mainstream?

..

No patch required -- hdparm (newer versions) already do this correctly.

I have hdparm v8.9 here, is that new enough?

Thanks for you help,
Soeren
