How
to erase data efficiently
You could imagine
that by simply formatting your hard drive you
will prevent anyone from accessing your stored
data, but in reality this is not the case. There
are methods to recover data from the disks, even
if they have been overwritten. Even though some
data recovery methods are not available to all,
you should make sure that you are not sharing
important private and confidential information
without your knowledge.
From our experience, also confirmed with several
external sources, it is necessary to carry out
a logical erasure in order to ensure safe data
deletion. This logical erasure consists of several
passes of writing, some with random data and others
with fixed data, over each sector where data is
stored. The safest option is always the physical
destruction of the disk plates where the original
information is stored.
