[Solved] Acoustic Management?

I am not sure if Automatic Acoustic  Management (AAM) is even possible; I've read rumours that it is not really implemented, despite what is reported by S.M.A.R.T.

Anyway, in order to possibly reduce the noise from my computer I tried this command:

$ hdparm -M 192 /dev/sda

/dev/sda:
setting acoustic management to 192
HDIO_DRIVE_CMD:ACOUSTIC failed: Bad address
HDIO_DRIVE_CMD(identify) failed: Bad address

$ hdparm -M 128 /dev/sdc

/dev/sdc:
setting acoustic management to 128
HDIO_DRIVE_CMD:ACOUSTIC failed: Bad address
HDIO_DRIVE_CMD(identify) failed: Bad address
$

***

S.M.A.R.T., via 'hdparm -I', recommends the above values for the two disks.

Am I using a bad command, or is there another explanation for the "Bad address" message?

I don't know why you get those messages, but it is the right command, and it does make a difference (less vibrations).

Thanks. At least I seem to be on the right track... I might add that this is on an AMD Athlon64 system with a Gigabyte MB and what I would consider a vanilla setup - i.e. the disks in question are ordinary PATA disks. Strange.

Edit: I was on the wrong track entirely: I had given the command as user, not as root. Given as root, the response is the following:

bash-3.2# hdparm -M 192 /dev/sda

/dev/sda:
setting acoustic management to 192
acoustic      = 192 (128=quiet ... 254=fast)

Sorry for this silliness...
