					Why Wipe Hard Drive Space - Much better Ways To do It
As computers turn out to be more and more popular for use in nearly every aspect of
human endeavor, the question of data security also becomes essential. That is, with the
rise of computers also comes the rise of digital storage of information, because it is in this
digital form that they could be accessed by computers. Digital storage comes in the form
of compact discs, flash memory devices, and hard disk drives (that are presently the
standard and generally are built into most computer setups).

Now, physically securing the digital storage devices under consideration is of course a
choice. However this may not always be feasible. For example, these devices may be in
regular use by a number of people, and restricting access would simply become

Password protection is yet another choice, when talking of digital data security. However,
the security afforded by passwords is determined by the strength of the system being
used, and also on the passwords used themselves. Passwords that are easier to somehow
guess would result in weaker security than passwords that are harder to guess.

There are instances when neither of these two security options is feasible, nevertheless.
For instance, it may be preferred that each one of the data on the hard drive is
permanently removed. Normal deletion (using the current operating system on the
computer, for example) doesn't eliminate all of the traces of deleted data. In this case,
security can be improved by performing a hard drive wipe, as an alternative.

A hard drive wipe is a process carried out on a hard drive to help ensure that all of the
data and information on the drive are removed beyond possibility of recovery. This gets
important when a computer changes ownership, for instance, or when a hard drive or
computer is to be disposed of. In both of these situations, potential access to deleted files
might lead to the unintentional exposure of confidential information.

How does a deleted file still have traces on the hard drive? Well, when a deletion is
carried out on the file, it is marked ‘deleted’ and the space it occupied is made available
for new use. However, the data on the actual hard drive corresponding to the deleted file
is in fact not removed or overwritten. So the data on the hard drive is still there, even
when it's hidden from plain view. There exist software utilities that can facilitate the
process of recovering the content in these theoretically deleted files.

A hard drive wipe helps to prevent this by really overwriting all data on the hard drive
with random sets of data. This makes it next to impossible to figure out the data on the
hard drive to recover any of the deleted data.

Many hard drive wipe programs carry out this overwriting process several times, which
will increase the security provided. You will find also numerous algorithms utilized to
generate the random data with which the existing data is overwritten. The better
algorithms produce random data that's closer to being truly random, making it even more
difficult to try to recover the original data.
