command divides
the
disk
Into
sections
calleo blocks, and
it creates
a table
of
contents,
called
a
directory
or
catalog, on the disk The d<skname can be
any

1
6 characters long The
i
d. number
is
any 2
characters.

a unique id
number
Be

you
HEADER
a
disk
because
Ihe HEADER command erases all sioreo data Giving no
id. number al'-ows you to perform a quick header. The o(d
id. number
Is used. You can on'y use ihe
quick header
method If
the disk
was
previously formatted, since the quick header only clears out the
dkecto'y rather than formatting ihe disk.
