relationships
with
the
Hidden
Protected
Area
(HPA)
This
section
provides
information
about
the
purpose
of
the
Hidden
Protected
Area
(HPA)
and
the
relationships
that
exist
between
the
HPA
and
the
ImageUltra
Builder
program.
Additional
information
about
the
HPA
is
available
from
the
Lenovo
Web
site

What
is
a
Hidden
Protected
Area?
Implemented
in
2003
on
selected
models
of
ThinkPad
and
ThinkCentre
computers,
the
Hidden
Protected
Area
(HPA)
is
a
variant
in
the
Lenovo
disk-to-disk
recovery
scheme.
Like
the
service
partition,
the
HPA
provides
its
own
operating
environment
and
contains
operating-system
modules,
application
modules,
device-driver
modules,
and
a
set
of
recovery
tools.
But,
the
similarities
stop
there.
The
architecture
of
the
HPA
provides
a
secure
environment.
Protection
settings
(security
levels)
and
access
to
the
HPA
are
controlled
by
the
computer
basic
input/output
system
(BIOS).
The
HPA
does
not
rely
on
a
boot
manager,
and
is
therefore
immune
from
boot-sector
viruses,
which
could
cripple
other
disk-to-disk
recovery
methods.
Each
application
within
the
HPA
is
contained
on
its
own
protected
service
area
(PSA).
There
are
two
types
of
PSAs:
Boot
PSAs
and
Data
PSAs.
Boot
PSAs
contain
all
of
the
files
necessary
to
boot
and
start
the
application
from
the
associated
Data
