Methods Of Secure Hard Drive Destruction For Your Needs
1. Secure hard drive destruction is varied and the
effectiveness differs from method to method. In order to
proceed, the individual has to know them and achieve an
understanding of the effectiveness of each method. There
is a certain amount of expense involved with this
procedure. This depends on the type of removal required.
2. One method of clearing information from a storage device
is to overwrite it. Overwriting is basically writing over the
unwanted information in a pattern. The written pattern is
a numerical series, over the stored content.
3. 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.
4. 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.
5. Degaussing is another means of erasing sensitive data.
This involves the use of a tool devised to perform this task.
The result is a device that cannot be used.
6. To date, the best way to eradicate data from the system is
to subject it through physical means, such as shredding
the device. Another way is to change the state of the disk
is by vaporising it. For the ecologically aware, there are
some companies who will advertise the eco-friendly
nature of their practices involving secure hard drive
destruction.
