Do you really know
what’s on your hard drive?
| Sanitize |
To expunge data
from storage media (e.g., disk drives, diskettes, CD-ROMs,
and tapes) so that data recovery is impossible. Sanitizing
includes overwriting, degaussing and destruction. Clearing
data does not constitute sanitizing. |
Due to the way data is written to a hard drive, format or Fdisk
alone is not sufficient to remove data. After formatting, data may
remain in bad blocks and spare blocks and can be recovered by simply
reallocating spare blocks or unmarking bad blocks.
|
Software
solutions are the preferred method for sanitizing
expensive hard drives for redeployment, lease return or
sale in the secondary market.

If your institution is donating used PCs to
charity, make sure you sanitize the machines first in order to avoid
exposing sensitive or confidential data to prying eyes. It is NOT
sufficient to merely delete files. Either remove the hard drive
altogether, or utilize proper methods for removing the data from the
drives.
|
You
need to be aware that it possesses retentive properties
that cause data to remain, even after you may think
you’ve erased it. This is referred to as data remanence,
which is the residual physical representation of data that
has been in some way erased or cleared.
|
To properly sanitize a drive, ALL data must
be removed and overwritten at every addressable location on the
media. An effective Solution writes to active and inactive file
space, bad sectors and tracks, the space between the end of a file
and the end of a block or sector, file allocation tables,
directories and block maps. This process assures information
is unrecoverable by technical means.

If you are in
the HealthCare field then HIPPA compliancy should be at
the top of your list of concerns.

Computers contain information that must be kept
confidential application data, licensed software, licensing keys,
passwords, email, and other sensitive information. Deleting selected
files from the computer and even formatting the hard drive (s) does
not prevent subsequent recovery and use of this information by
unscrupulous individuals using commonly-available applications.
Media sanitized by destruction cannot be reused,
however software overwriting solutions do not harm physical storage
devices so they can be reused.
Degaussing causes the loss of timing tracks and
renders a hard drive inoperable.
