New HP disk
declassification capability
If
you are in the aerospace, defense,
or electronics industry, you may be
concerned
with
information left on
magnetic
medla after it has been
erased, a problem
hown as
magnetic remanence.
This
problem
typically occurs when you want to
move a disk from one location or
project
to
another.
One method
to
solve
this
problem
has been outlined by the U.S.
Defense Investigative
Service (DIS)
and is contained in a document
called Department of Defense
Magnetic Remanence Security
Guideline.
T~E
guideline specifies
that the disk
medla be overwritten
'n' times with a specified bit pattern.
Although
thLs
requirement
is
not
new, an approval process
is
now
required stating that the erasure
procedures meet DIS requirements.
The DIS recently approved the
Hewlett
-
Packard procedure
for
declasslfylng
HP
disks.
Hewlett-Packard's software utility
for declassification
is
supported
only on
I-IP-manufactured single

ended small computer standard
interface (SCSI) 3%
-
and 5%

inch
form factor disk mechanisms.
Included are both

isms and mass storage solutions
containing those SCSI mechanisms.
