There has for long been a misconception among people regarding deletion of data. This misconception is that data that is deleted using simple methods like the Shift + Delete keys or the command prompt methods are deleted forever. In reality the files deleted in this manner are still very much existent on the hard drive, but they just become invisible as the operating system considers them as deleted. As the data is still very much present, a good data recovery software can easily salvage the data from the hard drive. This is the same when it comes to permanent deletion of data, when people use these methods to delete the data, and they are forced to believe that the data has been permanently deleted, while permanent deletion was possible only by using a file eraser or a disk wipe utility.
However, they realize that they were wrong when a trouble maker, accesses the data on the hard drive of the user, steals the user's personal and confidential data and misuses it in many ways. This is a common experience among many users, and the data recovery software makers came up with a disk wipe tools and file eraser software that used technology similar to the one used by military agencies worldwide. As overwriting needed to be done multiple number of times, various methods of overwriting were used for deletion of data.
Not only were utilities that the user could make use of to erase specific files developed, but disk wipe tools that could erase an entire hard drive. This made the file deletion procedure easier for the user who had less time on hand to get rid of files.
