The number must be

How
fflany
heads
to
use?
Enter the
number
of
heads
to
allocate
to
the
logical drive
You
cannot
allocate
more
than 4 heads
to
the
drive,
Other
than
that,
you
can. allocate
as
many
heads
as you want, from
the
starting
head
to
the
ending
head
of the logical
drive.
For
example,
if
me
starting
head
is
Head
2,
you can use as many
as
3
heads, which are Heads
2,
3,
and
4
If
you have a 15-megabyte hard
disk, the disk
has
6 read/write
heads
per physical
drive.
Since you
can
allocate only 4
heads
lo
each
logical drive, allocate the
2
extra
heads
to
second
logical
drive.
