HDPARM won't set Automatic Acoustic Management (AAM) value

[w.edelberg]

Hello,

What I am trying to do: I have a dual-boot system with Linux Mint 14 "Nadia" and Windows 7. It runs fine under Windows 7, but there is a great deal of intermittent hard drive noise (fluttering sound) when running Linux Mint 14. From what I've read online, this might be fixable by using hdparm to reset the Automatic Acoustic Management (AAM) value: "sudo hdparm -M 128 /dev/sdc".

The problem I'm running into: Okay, first I am using "sudo hdparm -I /dev/sdc" to see what the current AAM setting is for /dev/sdc. I get back a lot of information, but this looks like the relevant part:

Advanced power management level: 254
Recommended acoustic management value: 208, current value: 0

Now, when I try to reset the AAM value, this is what I get:

walter@jupiter-linux ~ $ sudo hdparm -M 128 /dev/sdc

/dev/sdc:
setting acoustic management to 128
HDIO_DRIVE_CMD:ACOUSTIC failed: Input/output error
acoustic = not supported

I get similar error messages when I try to set the value to 0, 208, or 254. I should mention that the drive in question is a Seagate Barracuda Black 2TB, Model Number ST2000DM001-9YN164. (At first I thought that the problem might be that this particular hard drive doesn't support acoustic management. But if that is so, why do I get back 208 as the recommended value, when I use "sudo hdparm -I /dev/sdc"?)

Thanks for any help anyone can provide.

Seagate drives really don't support acoustic management, since many years.

Thanks eanfrid. That saves me from the wild goose chase I was on, trying to get AAM to work on my Seagates. I see on Wikipedia that in 2011 Western Digital joined Seagate in not supporting AAM. The sound of the drive is pretty annoying. I wonder whether I could lessen it either by rolling back from Mint 14 to Mint 13, or by reformatting the drives using ext2 or ext3. Right now they are ext4. Any thoughts on that?

Changing the file-system or the kernel will have no consequence. It is purely a hardware matter. I have 2 of these drives in a RAID1 2GB ext4 array since about 1 year and I don't feel that they make so much noise.
