Here, the functions of the AMM, the full name is called "Acoustic Management Mode (sound management)", which is working hard disk drive manufacturers to reduce the noise of a proposed technical specifications. Works to reduce disk seek time, to reduce the noise when the hard disk Seeker, in line with the standard hard drive to open AMM feature, hard drive seek noise can be reduced by 10 ~ 20%, while the performance is only reduced by 1 to 3%, can be described as The small gain big.
Unfortunately, although the market have all brands of IDE hard drive supports AMM technology, but in order to ensure efficiency, most manufacturers in the hard disk automatically when the factory closed AMM function. By AIDA32 (http://www.skycn.com/soft/8258.
html, you can check your hard drive is supported or has open AMM function). Shown in Figure 1, the writer on this piece of Maxtor hard drives support AMM. If your hard drive support AMM features, but is not open, then how do we open it manually?
Hitachi and IBM hard drive users
If you are using a Hitachi (including IBM) or Maxtor series drives, so blessed, because the two companies offer a dedicated sound management tool, and is completely free.
Hitachi (IBM) hard drive users
If you are using a Hitachi or IBM hard disk, you can use Hitachi hard disk drive management procedures Feature Tool (www.mydrivers.com/dir84/d33720.htm), the latest version is 1.92, this tool allows users to manually open the hard drive Automatic Acoustic Management feature (AutomATic Acoustic Management). Currently Deskstar 40GV, Deskstar 75GXP or updated models of IBM and Hitachi hard drive can support this feature.
Double-click download running back Hgst-ftool_v192.exe program here will be asked to insert a blank floppy disk, click "Next" button will automatically create a system can boot IBM DOS 2000 system disk, boot disk with this system , will automatically run the Feature Tool program, the program will show the detected hard disk information, as shown in Figure 2, including the Model name (Model), Serial number (serial number), Driver capacity (capacity), Cache size (cache size ), Frimware (firmware version number), Acoustic management (sound management), Max.ultra DMA mode (the maximum transfer mode) and so on.
If your hard drive does not support the AMM function, "Acoustic management" This one will appear as "Not supported" the words. If your hard drive support AMM function, the default is displayed as "Disabled", then we can "Features" menu, select "Change Acoustic Level" item, then you can start the Automatic Acoustic Management, shown in Figure 3, there are three ways to choose from:
Disabled: Close AMM;
Enable (Recommended value): default recommended values, the proposed selection of the;
Enable (User defined value.Use arrow key to select): User defined, you can choose between two different operating modes, "Quiet Seek Mode" said the quiet, low noise mode, the lowest noise at this time, it drives the efficiency of the relatively low; "Normal Seek Mode" that high-normal mode, then drive at full speed, but the highest noise. Quiet and Normal modes in between the 255 choices, you can adjust as needed, adjustments can click on the "Test" button for testing.
Maxtor hard drive users
Maxtor's sound management tool called "Acoustic Management" (www.mydrivers.com/dir44/d17676.htm), the latest version is 4.0 (the version released back in 2001, has not been upgraded), note that only the DiamondMax Plus 40, DiamondMax 60, DiamondMax VL 30, DiamondMax Plus 40, D540X, D740X or updated models of the hard disk can use the tool, unfortunately, does not support the Quantum hard drive.
Download back is a self-extracting file named Setacm.exe, after decompression can be Amset.exe, Chipset.drv, Amset.txt three documents, its main executable file is Amset.exe. You do not have to reboot the system to DOS mode, the implementation process, directly in the command prompt or MS-DOS window to run on it, but the caller must add the appropriate command parameters, as shown in Figure 4, the command parameters actually equivalent to different noise levels:
amset.exe / quiet: Quiet mode seeker, then the noise significantly reduced, but disk performance is also decreased;
amset.exe / fast: Quick Seeker mode, noise reduction at this time, a certain decline in disk performance;
amset.exe / off: turn off noise reduction features, the highest hard drive performance at this time but the biggest noise;
amset.exe / check: you can view the current operational status of the hard disk noise reduction features.
The choice easier
If your hard drive is not in the two instruments within the scope of, and use the Feature Tool is not willing to bite the bullet, as long as the hard disk support AMM, then there is an easier option:
Provided that you are using the Intel 8xx chipset motherboard, and installed IAA (Intel Application Accelerator, Application Accelerator) software (www.mydrivers.com/dir63/d25237.htm), then you can set the window in Figure 5, the hard disk The Automatic Acoustic Management feature, the default settings of the feature has been closed. In the "parameter data" drop-down list box has several different options, such as the "highest performance," said the hard work in the most efficient at this time but the biggest noise, "minimum sound output" is definitely the efficiency of the noise is relatively low, but not high, you can set the work to be done.
Now, the dead of night, I believe the hard drive to open AMM function given by a little noise will not disturb your family no longer has it!
