Free Harddisk Cloning Solution

I am sure there are times you need to move all harddisk content over to another disk without the luxury of the time to reinstall.
Here is the free Home-Based solution just by using a <1GB Thumbdrive you can image your harddisk without buying software like Norton Ghost or Acronis.
First download unetbootin, a tool to create Linux Live Thumbdrive boot disk.
Next download EASEUS Disk Copy from EASEUS.
Unzip dc.zip to a location.
Create a bootable thumbdrive by launching unetbootin as shown.


After that plug in your source and destination harddisk, boot from thumbdrive then run disk copy and do a sector by sector imaging!

New Stuff I discovered regarding temperature control

Recently I updated all my drivers again but soon I realized that my laptop was running hotter than usual.
I mean really hot like 60 degrees on Idle.
I soon narrowed it down to the latest chipset driver I install so I reverted to the old driver and surprisingly it went down.
I took a look using HWMonitor and found that the latest chipset driver was working the processor really hard consuming 25watts constantly on idle.
I downgraded the chipset driver to the previous version and the problem disappeared immediately.
So the story of this lesson is do not assume anything and anything newer shiny != greater.

So if you encounter heat issues you might also wish to try revert to old version.
Also for Windows 7 compatible machines setting the processor cooling management to passive means the fan will spin less (quieter) but it will operate at generally higher temperatures. In contrast setting it to passive mode means it will spin more (noisier) but keep temperatures lower.

Just A Query From Readers.

My opinion of the world today is rather negative.

I see people getting excited over silly devices like a iphone over more important matter like family, society, country and the world.

Superpower wage war over non-existent WMDs (even though the intelligence agency reported NO THREAT) and the leader got away with indirectly causing the death of the soldiers in his own country, in the country where in was fought burning away cash in the form of expensive weapons used. It is like mass murder in the public view of everyone and no one actually cares...

We also have filthy rich companies concern with saving money as a result causing pollution over the environment and putting a price tag on it. IMO money can never buy back the same state it was previously.

In the 21sth Century IMO mankind has sink to unprecedented depths again...but this is worse given that it was caused by apathy not by a single country but by people all over the world.

In my country (Singapore) a lot of parents are both working neglecting kids just to get a higher standard of living to purchase useless stuff like the iphone which almost cost a laptop not to mention the exorbitant monthly subscription.

People start engaging in trashy shows and useless advertising instead of reading useful materials like books.

In my country students study just to pass exams...

Does that happen all over the world or is it just my country? What is your opinion on this?

The 100MB Partition in Windows 7

As you might already know Windows 7 default installation creates a 100MB partition during Setup.
The function is not really documented on the Internet, however reading this you should already know what it is for.


The partition in question is the System Reserved Partition.

So lets compare the Windows 7 installation with and without the 100MB System Reserve Partition.

Firstly lets take a look at the root drive of the Windows 7 with the 100MB:


Next lets take a look at the root drive of the Windows 7 without the 100MB:


So what is the the difference? It is the presence of file and folder required for booting like bootmgr etc...

Open up the 100MB partition and what do you know we are right!


So what does this means?
It means in actual fact the extra partition is optional has 0 effects on system operation.

So lets take a logical approach and think of possible reasons for this change.

1)Prevent Noobs from accidentally killing their Windows Installation by moving the boot files off C:\ to a partition they can't touch? Possible Very Likely
2)Optimize boot performance by moving boot files to the first partition(front part of the drive)? Possible as well.
3)Modularize the OS file layout? Very possible a much more elegant solution than cramping all the files into C:\.In fact it could mean you could multiboot multiple Windows OS on volumes without having repeated Boot files in each and every installation.

What does this means to end user? It means for those Dual Booters like me it is 4 - 2 primary partition left instead of 4 - 1.
Does it matter? No because you can create logical/extended partition to bypass the 4 primary partition limit in legacy Master Boot Record (MBR).
It doesn't affect GUID Partition Tables (GPT) on EFI systems.
Unfortunately Windows 7 doesn't do GPT volume installation.

So remember the 100MB is just a rearrangement of boot files. Period.

Audio Driver Matching

The reason for this new post is because I found out something interesting about MSI Release Audio Drivers.
Compared to Acer Default drivers they are richer in sound yet utilities the same audio chip.
However going by their filename I believe it is device id optimized.
So how do you find out the audio chip in your laptop desktop?
Go to Control Panel, open up Realtek Audio Driver Control Panel and check the audio chip used.


The Audio Codec will be listed.
Further proof that Audio Codec is dependent on Audio Chip installed and not device driver:


So which MSI driver to use?
Check the filename: ad_alc888s_vc2_6.0.1.6151_al00.zip
This indicates the driver is optimized for the ALC888S Audio Chip in the laptop.
I listed all the device driver on MSI by the Device ID just download & install!

"THX Certified + 4 Premium Sound Speakers" Driver

ad/ad_alc269q_X_al00.zip

ad/ad_alc269_X_al00.zip

"Sound by Dynaudio with DTS Surround" Driver

ad/ad_alc888s_X_al00.zip

ad/ad_alc888_X_al00.zip

ad/ad_alc662_X_al00.zip
