Antec P183 HDD Silence: AAM (Automatic Acoustic Management)

hard drives make noise to contain mechanical parts, and major sources of noise from the spinning disk itself (a 10000rpm, 7200rpm, 5400rpm, etc., Depending on the disc) and of the playhead in reads and writes. For these disk reads and writes need to do a search operation "seek" it makes the most noise on a disk (which we hear sounds like a kind of "scratching"). This noise can be reduced by using an option that has hard drives known as AAM "Automatic Acoustic Management" Introduction

Most methods to silence a hard drive requires changes to hardware, such as encapsulated trade or craft "(such as this that you see on this article coolpacks encapsulated), or methods of decoupling of the disc transimisión the box to avoid vibration (silentblocks, suspend to disk with rubber, etc.).

An easy, requiring no physical handling of the disc, to silence the hard drive is by enabling this feature. The small downside is that usually there is a slight loss in disk performance, in exchange for that child seek mode noise. Supported Drives

Not all discs have this feature. For example, the Seagate drives do not have from the 7200.7 versions, there are rumors that intellectual property issues. Instead brands do have this option in almost all his albums, such as Samsung or Western Digital, which are leading brands in terms of silent records are concerned. In fact, at present 3.5 "quietest are the EcoGreen Samsumg and Western Digital Caviar Green, which we discussed in this news .

Another thing to consider is that some discs The entitlement of AAM is not just a difference in the sound of the disc, so it does not compensate enable it (why waste performance if you did not win anything ...).

Below is a list of the biggest hits silent, where you can see if it is possible or not enabling AAM, and if so the difference in noise is the enable or not (data from SilentPCReview ) :

An overview of these data, and others can be found online:

Drives that support the AAM setting:

Western Digital Caviar Series, Raptor Series. Samsung
: I know of none that supports it.
Seagate Barracuda IV series (they are quite old), from this series are no longer seagate AAM.

Discs that is not worth enabling AAM:

Western Digital Raptor X (supports AAM, but there is no appreciable difference between enable and not to).

How to enable AAM

To enable this option, manufacturers often provide their own tools, so you should go to the manufacturer's website and download the necessary tools. For example, Samsung provides HUTIL , Western Digital or their own tools Hitachi Feature Tool

One of the most popular is the Hitachi, the "Hitachi Feature Tool" , which also works perfectly with Samsung and Western Digital drives, and is the one I have ever used (I I used for my samsung HD401LJ, HD501LJ, my WD Caviar GreenPoint).

This tool has the advantage of not operating system dependent. Creates a boot floppy or CDROM and booting from that medium can run the Hitachi Feature Tool Complete instructions of a program, you can find here, but I'll do a brief summary in English: First

is to create a boot disk, then:

Run the program you downloaded: Feature Tool-install.exe
Insert a 1.44MB floppy disk in the floppy
Follow the instructions

Another option is to create a bootable CD and for this:

Find the CD image file that you downloaded
Use any program that can record images (. iso) to CD Burn CD

Once we have created the diskette or CD boot, follow these steps: Restart the PC

and access to the BIOS (delete key or F2, or similar, depends on the motherboard)
In the menu changes, we give priority to the PC boot floppy or CD (in our case), to ensure that the PC will boot from the device you just created
We recorded the options, and then restarted we
The PC should now boot from the selected device, and start the program "Hitachi Feature Tool."

The program looks like this:

In the "Features" can find the Change Acoustic Level (first choice):

And once we have these options selected to choose from:

AAM can enable selecting the second option (automatic) or the third option (custom). I recommend the third option, which allows changing the AAM selected from a range of options:

Every time we select a test to see hear the noise of the disc. It is advisable to keep trying, because many of them there is not much difference in noise, and let selected the highest possible we seem quiet (to have minimal loss of performance possible.)

By default the disks often come set to performance mode, ie with the maximum possible value.

Once we made the changes, we give OK and exit the program. And we have our album with AAM enabled and quieter searches. Other utilities

There

additional tools we can use, in addition to the manufacturers that we have mentioned above. Are software tools that run under an operating system, so they have the limitation that we need the appropriate program has support for your operating system. Many of these applications do not work on Vista or Linux.

HDDScan

Select "Tasks" menu we can find a "Features" where you can select "IDE Features" and find the following screen:

in which we can enable the AAM. This program runs on Windows XP and Windows Vista, even works perfectly on my Windows Vista x64, so it is an interesting alternative to the Hitachi Feature Tool

CrystalDiskInfo: Another program that lets you change the AAM, created by Crystal Dew World, which for many years because they are also sound CrystalCPUID program developers that allows change voltages and frequencies of our micro software. Also control other features of the disks (SMART monitoring through the disc), and we care, the AAM is selected from the following menu:

Once selected we will see a screen like this to select the option you want for AAM:

This program also works with Vista and Vista 64 bits.

Notebook Hardware Control: This tool is best known for its ability to change frequencies and voltages of buses and graphics software, especially in laptops (for buses in general are more practical than other programs mentioned in this article other).
systool: Another tool of "tweaking" general, which also allows you to change voltages and frequencies, in addition to what we want in this section, enable AAM:

Same as above does not work in windows vista, although it works on windows XP, windows 2000, windows 2003, and even 64-bit versions of these systems.

HDTune Another application that allows us to enable AAM (photo courtesy of the forum CrashNukem n3D):

One of the drawbacks of this program is that the free version does not allow this option and we can only use the retail version to have this functionality.

WinAAM: This application is the simplest we can find:

has a major drawback and that works only with ATA disks and not SATA drives. Moreover, there is a Mac version
