One of the most indispensable tasks of a computer is storing or processing information. Information can be as commonplace as email messages or simple lists, but can also be as highly important and confidential as internal communications or client information. With computers being used for handling top-secret information, security measures have become an increasing concern.
To make it more secure we use some security option and one of them is physical security. Putting computers that handle important information in a location that is inaccessible or physically guarded greatly reduces the possibility of unauthorized viewers to access your data. However, this security measure may not always be practical and may not also even be possible at times.
In this case, you can resort to software-based security measures. Among these include data encryption and password protection. These can protect your information from being accessed by unauthorized viewers. However, security measures, both physical and software-based can only do so much. And there is still a possibility for a hacker to access information that is only protected by a combination of these kinds of security. Simply put, these are not always foolproof means.
Moreover, these security options are usually no longer applicable in the case of data erase from a hard disk when you were selling your pc or giving to someone else. You might think that a reformatted hard disk no longer contains useful information. But a hard disk may still contain file data especially if it is not securely wiped.
This is due to the fact that deleting ordinary files or reformatting does not automatically get rid of the data stored in files from the hard disk. A marker or tag is only placed on the deleted files that gets rids of them from directory listing and provides available space for later use. Physically, the data is still on the disk unless it is overwritten, and it may not be possible unless the data has been compromised already.
Even more secure than reformatting is a process called disk wiping. The term disk wiping is not only used in reference to hard drives but any type of storage devices such as CDs, RAID and others. Drive wiping is a secure method of ensuring that data by the use of drive wipe softwares because previously stored data can be brought back with the right software and applications, the drive wipe 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 overwriting.
There is lots of disk wipe software on internet.
