How to Permanently Erase Data Off a Hard Drive

“I want to sell my old HD but my friend told me not to do as any nosy purchaser can get into disk with recovery software.”

What happens when we delete files from our computer using the Shift+Delete command ?? Most of us think that the file is completely removed. But in actual case it is not.  So what happens then ?? The files are allocated a space of memory in the physical hard drive every time we move it there.Image

And when we perform the most common permanent deletion that very allocated space is freed & gets ready for saving another file there. The deleted file remains recoverable until something else new file replaces it. So how to permanently delete a file which makes it UN-recoverable.

Here what you will do

1. Format the drive. Which is obviously the first & best choice.
2. Or replace the old files with random data which can be achieved by using certain(or most) data wiping software.

Here some most useful free software’s.

Download Darik’s Boot and Nuke (DBAN) here. Two different versions (one for PCs and newer Macs, and the other for older Macs) allow DBAN to work on nearly every computer made within the last ten years.


Eraser is a free & open source software that works with almost all Windows Operating Systems including DOS. You can delete a file or folder or simply a complete drive using this software.

This is for techies so if you don’t get it ignore it simply..

  • The Guttman Method : This theory is based upon Peter Guttman theory “Secure Deletion of Data from Magnetic and Solid-State Memory“. This is the most secured file deletion process. The data deleted using this concept is overwritten 35 times using carefully selected patterns. But like all other most effective ways, this is also very time-consuming.
  • US DoD 5220-22.M : This concept is based on the United States Department of Defense recommendation 5220-22.M. Like the Guttman concept it also overwrites the data but in this case the data is overwritten 7 times only. Well this is secured but not as much as the earlier one. But this is time saving other hand.


(remember this is file or drive level software)


Active Disk Wiper FREE version, Powerful and compact software that allows you to destroy all data on hard disks, USB drives and floppy disks completely, excluding any possibility of future recovery of deleted files and folders.

It’s a hard drive and partition eraser utility.


Hope this will work rather you want Ultimate satisfaction. Then take a 5″ hammer, place HD on floor hit as hard as base ball. Then throw it to tamez river.  🙂

Apart from hardy joke these three method can do something better or you can use combination of them.

Punjab got UBUNTU fever !!

Sir i got a mess at my laptop.

I got a laptop in Punjab Government Youth Program scheme but i m searching a teacher now who can tell me how to use this machine.

From Punjab government,s youth initiative scheme, “Taking Punjab to a digital future”thankful to Mian Shahbaz Sharif and Mian Nawaz Sharif for thinking about the youth. The laptop distribution ceremony held at The University of Punjab new campus Lahore, on 23rd March 2012 and so on all over the nominated universities in Punjab.

But there are a few problems that most of the successful candidates experiencing got stuck in UBUNTU when using the Dell N4050 laptop got from Punjab Gov for the first time. The main issue is that when you open the box and start the system. This is where the whole headache begin. You must be GURU of Operating systems or have some past experience of Linux flavors (which is not common in Pakistan). Now mostly students caught in MS office documents conversion (as when they go to Labs or Win Based Pc’s their word files are in “XML” while mostly MS-office(MS office2003) recognize “RTF” or “DOC” extensions).

Or the students are not comfortable with Ubuntu or Open office environment. Now here stage comes to migrate in Win7 platform. But when you install Win 7 its gives

“BOOTMGR is missing” PressCtrl+Alt+Del to restart message error.

Here is the solution what i found to prepare your system for Win 7 installation.

> first Insert DRIVERS & SOFTWARE cd and copy at least two folders drivers for “Win7 32bit n

Win764 Bit” or you can only copy Win32 if you sure that you are going for only Win32 on USB.


> Go to bios setup just after booting keep pressing “F2”

>  In “Advanced” option go to “SATA Operation”

> Change “AHCI” to “ATA” Confirm the settings By pressing yes, Save settings and EXIT

> Restart PC

> Press the F12 key soon after restart

> select BOOT sequence DVD/CD as first priority

> Delete and Format all the partitions.

> Choose the partition in which you want to install the windows and follow the steps.

IF you have already deleted the Ubunto operating system:

  1. boot from win 7 DVD and when you see option of start installing windows, click on another option which should be Repair windows.
  2. when it prompt you to insert system restore or windows image file, press the browse button and eject the win 7 DVD.
  3. insert the Driver CD then browse the CD and left click on the folder named “Educational software and Drivers Pack” and click copy. Now go back and browse some other partition and left click and Paste.(this will take more then 15 minutes to complete the paste) 
  4. after success full copy, install the window 7 by following (a1 to a6) steps
  5. after installation and starting the windows it is time to install drivers.
  6. go to the software folder which you copied.
  7. no need to go in a sequence
  8. just double click on files in every folder and click on OK.  (Be aware which architecture of window you are using 32bit or 64bit?

> VERY IMPORTANT. after first restart, you will see a small pop up that asking for make and model of your laptop. DO NOT SKIP , keep pressing arrow until you see DELL and then enter N4050 in the empty box under the logo of DELL and press OK.

Hope this info will work for you, Write free for any suggestion.

Deal with stick

Aiplex Software is a company based in India contracted by the MPAA to deliver copyright notices to websites that they deem violate copyright laws, and distributed denial-of-service attacks (DDoS) to said sites if they fail to remove the offending content. Both Aiplex Software and the MPAA were subjected to a DDoS attack themselves as a result of said contract.

Aiplex have openly admitted to engaging in illegal actions such as Distributed Denial of Service attacks against various anti-copyright websites. In September 2011, Aiplex began sending requests to bloggers to remove the content and links of articles that reported on Aiplex’s use of DDoS attacks, claiming that such media coverage was “defaming the company’s image & its prospects.”

Aiplex has also sent a misunderstood request to “takedown” content to Techdirt, claiming defamation on content on a website unrelated to Techdirt. Techdirt states in their article “First of all, they used our copyright notification email, and this issue has nothing to do with copyright. Second, they are asking us to remove our content from a site that is not ours, and which we have no control over”…”Anyway, seeing as we don’t control the web page they’ve asked us to take down, we obviously won’t be doing a damn thing about it, other than to publish this post and hope that, sometime in the future, Aiplex learns a little bit about how the web works.”

Defaced theregister.co.uk

Another giant down, One of the biggest News website Theregister.co.uk has been hacked.  This time website was not hacked by traditional web attack like SQL Injection, Remote File Inclusion or local file inclusion. However DNS Hijacking or DNS redirection attack was used. In which hacker redirected website to his server. The website was hacked by Turkguvenligi who is also known as TG hacker and is also responsible for the major website defacement in past including Microsoft, Dell and other big websites.

If you would check the hackers zone-h record , You will find that this hacker only goes after major websites, It’s quite sad to see that even major websites don’t pay proper attention to their website security.
