The way to completely destroy the hard disk information
Do you know, the formatting of the hard disk will not actually be deleted. Rather, the hard disk drive information format can be easily retrieved.
When a drive is formatted, it only removes the old partition and then creates a new partition. The operating system can not read data for long time, but the data actually exists.
So when your old computer or hard disk is used by someone else, then they can get your personal information through the data recovery software.
So if you need to completely destroy the hard disk's data for any reason or your old computer or hard disk to sell it to others, it is very important to delete everything completely. So know how to do it.
1. Software (DBN)
Many know about Dariq Boot and Nuke or DBN software. It's a free tool, which offers the ability to completely erase the hard disk's data. DBN is a command line tool that is written to give instructions but it is very easy to use. Its job is to replace all the data on the hard disk into a finite data. Turning into finite data, it destroys old data and it is almost impossible to restore it.
There are several ways to use DBAN, but the 'Atonook' approach is the easiest. Atonuk completed the work in three steps, which results in the destruction of your data.
How to use DBAN
First download DBN ISO from http://dban.org site, then create Bootable Pen Drive. Now with this DBN Pen Drive, you will need to boot the computer boot (ie, restart the computer, select the bootable drive by pressing the F12 button from the keyboard). Press Enter with the autonuke command at the main prompt. DBAN will then automatically start wiping your drive and complete it with three passes, meaning that you overwrite your data completely and completely delete it.
Depending on the size of your hard disk's memory, this process may take several hours to complete, so it may be better for you to start this process at night. After this process of three steps is completed, the data on your drive will be completely erased and non-recoverable.
2. হার্ডওয়্যার
If you have less idea about software and you want to automate the process of deletion of data, it will be very helpful for you, the hard disk erase specific device (hard disk eraser). But these devices are not cheap price, the price is about $ 200. But if the number of your hard disk is high, then this device is very useful. The hard disk deletion device is very easy to use, just by pressing the hard disk on the device, the rest of the work will be done automatically.
3. To be broken
If you transfer the old computer after the purchase of a new computer, you can easily destroy the old hard disk. Hitting a hammer and nails on certain points of the hard disk is a great way to ensure that the hard disk is completely destroyed. What's needed for:
A hammer
Three nails (4-6 inches if good)
A small block of wood
