The Media Error Map
When you purchase your hard
disk,
a
few disk
areas called 'tracks"
may bo flawed because
of minor
defects
in the media or signals
from external
sources. However, no
hard
disk
is
shipped
with more
than
3
flawed
tracks per head
nor more than
9 {5-tneo.l or 12
{15-meg}
flawed
tracks
in
all
Track never contains
flaws.
Before shipment,
a built-in error detector dfiterminps which, if
any
tracks
on
your
hard disk are Hawed. Wo then
attach
to the bottom
of the disk a Media Error
Map
containing this information.
Keep

ir, if
your
drive
ever needs servicing.
In addition,
if
you choose 10 initialize your hard
disk
system
manually you may want to
reffir
to the
Media
Error Map when for-
matting
the
hard

discussed
in
Appendix A. We recommend it
only
for
advanced users who

not
meet system requirements
