HERE is the solution for HDD clicks & lags in Macbook Pro.

[naelamer]

Hello everyone,

Since I bought my Macbook Pro 13" 2.53 I replaced my HDD to 500GB 7200, but since then I can hear clicks from time to time and my macbook lags at the same time if Im watching a movie or anything.
I found a solution been explained by some PPL but its like no one trust the solution yet, now I tried it on my Snow Leopard, and I can say my problem is solveddddddddddddd.

Its too easy to try it by yourself if you face the same problem.

1- Find the attachment and unzip it somewhere on your HDD (I placed mine in Applications Folder)
2- Open your Terminal (You will find it at Applications>Utilities
3- locate your folder at the terminal by CD command
4- Once your at the folder where you placed the file write this command

hdapm disk0 max

it has to come back with successully message to you.

Now enjoy without clicking sounds or lags.

Im trying to make sucha batch file where I can place this command at the startup, if any clue please share with me.

ENJOYYYYYYYYYYYYYYYYYYYYY

How do we know this isn't a virus/trojan you wrote?

why should we trust something from an unknown source?

google this >> hdapm << and download it from the main source if u want

I think the performance upgrade 1.0 does the same thing and requires no restarts;

The performance upgrade you are referring to only applies to uMBP's with the 500gb 7200rpm drive and will not work for people with older MBP's who have installed this drive on their own.

Sorry, my bad.

I tried this performance patch, it does nothing really, still lagging

anyway, anyone knows how to make a batch file to run at the startup of snow leopard, this batch file will have a command with parameter!!
