Product
Recovery
program
The

The
Product
Recovery
Program
runs
independently
of
the
operating
system.
If
you
are
using
FDISK,
Disk
Management,
or
another
utility
to
reformat
the
hard
disk,
you
might
see
the
partition
where
the
Product
Recovery
program
is
stored.
Do
not
delete
this
partition
or
the
Product
Recovery
program
will
be
lost.
If
your
hard
disk
drive,
including
the
partition
where
the
Product
Recovery
Program
resides,
becomes
damaged
or
you
replace
the
hard
disk
drive,
contact
IBM
to
order
the
IBM
Product
Recovery
CD
to
recover
your
preinstalled
operating
system,
application
programs
and
device
drivers.
