In order to go through the process of secure hard drive destruction, an individual has to understand the various means and their effectiveness. Depending on the type of removal, this can be an expensive operation, especially for the less technologically proficient. There are cheaper alternatives, but they may only serve as a means to make it a little bit more labour intensive to retrieve the lost data.
A way of removing data from the computer's system is using the concept of overwriting. Overwriting uses a numerical system. This system is written over the information stored locally.
The data becomes difficult to read through the pattern of numbers. A more complicated form of overwriting exists, using this principle as a basis. This form of overwriting uses a mathematically based sequence of numbers. The information is then written over with that formula. This process makes it harder for complex systems to retrieve the information.
However this method is not a guaranteed success as the disk has to be in good condition in order for the data to be overwritten. If parts of the disk are damaged, the overwriting procedure cannot be performed for that device, leaving it with retrievable data. Overwriting is not always a satisfactory form of removal in establishments that require a higher grade of protection and implement stringent controls over privacy.
Another method of removing information involves the process degaussing. Degaussing removes data from the system, through the use of a specially built mechanism. The disk after going through degaussing is no longer functioning.
However one of the best means to remove content from a storage device is through physical eradication. Liquefying the device is one way. There is another way, which is shredding the device. This literally removes the data and prevents any form of retrieval. Some choose to have their devices vaporized. There are those with a sense of ecological awareness and there are companies who advertise ecologically sound secure hard drive destruction.
