hdparm -M acoustic management for sata disks?

hdparm -M acoustic management for sata disks?

[Soeren Sonnenburg]

Dear all,

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

# hdparm -M /dev/sda

/dev/sda:
 acoustic      = not supported

# sudo hdparm -M 254 /dev/sda

/dev/sda:
 setting acoustic management to 254
 HDIO_DRIVE_CMD:ACOUSTIC failed: Input/output error
 acoustic      = not supported

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

Thanks!
Soeren

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

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

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,

Ahh.. That part of the output just shows the "current setting field",
which is zero (0) or "invalid" in your case.   That's a display error
in hdparm -- it probably shouldn't bother with that field when the
feature is missing from the feature list that is given lower down
in the output.  (the reason it doesn't discard it today, is that early
drives had the feature but didn't report it lower down.. but we can
distinguish those drives by ATA version number now).

Here's hdparm-8.9 on a drive that *does* support the feature:


$ hdparm -I /dev/sda | grep Acoustic
           *    Automatic Acoustic Management feature set

$ hdparm -M /dev/sda

/dev/sda:
 acoustic      = 254 (128=quiet ... 254=fast)

$ hdparm -M128 /dev/sda

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

$ hdparm -M254 /dev/sda

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

..

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).

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

OK, I guess I have to accept that the drives I have here just don't
support AAM - just couldn't imagine that rather new 750G drives etc
don't have that feature :( 

Thanks for the clarifications,

Yes all of them were seagate drives.

So just bad luck... I should simply not have exchanged that noise fan -
now I head the hard-disks seeking...

Am I guessing right that samsung, hitachi et.al just do have support for
AAM?

Model Number:       SAMSUNG HD501LJ

Recommended acoustic management value: 254, current value: 254
           *    Automatic Acoustic Management feature set

My samsung drive supports it, but I do not hear any difference at
all.

Among the most quiet drives I ever used are the samsung PATA
(spinpoint) ones.

A lot of drives dropped the acoustic management stuff internally. If I
remember rightly there was a patent dispute about it just after it got
into the ATA standard.

Well, it was a neat surprise to me when I discovered that a newly
purchased - not Seagate which I almost always used - drive has all
the acoustic stuff in place.

ATA device, with non-removable media
	Model Number:       Hitachi HUA721050KLA330
	Firmware Revision:  GK6OA70M
	Recommended acoustic management value: 128, current value: 128
    *	Automatic Acoustic Management feature set
...

And it's indeed more quiet when seeking if acoustic management value
is set to 128, and quite more load when set to 255.  Speed decreases
a bit (I didn't do any measurements), but not much.

Western Digital drives also has acoustic management in place.  At
least some of them.  But I never heard of this stuff present for
Seagate drives - my guess is that those are in a "good" compromise
between speed and loudness already :)
