keep

Write
Protect
Notch.
When this
is covered,
the
disk-drives
cannot write
(change infor-
mation)
on the
diskette. Do
not
pinch the tab
into the
notch when you
apply it. If the tab
becomes
indented,
the
disk drive may
not
sense
that the
disk is
write-protected.
Leave
the
notch
uncovered
if you
want to
save or
change
information on
the diskette.

Diskettes
In
general,
handle
diskettes
carefully,
using
the same
precautions you use
with
tape
cassettes
and
high-fidelity
records.
A small
indentation, dust
particle, or
scratch
can
render
all or part
of a
diskette
unreadable
—
permanently.
•
Keep
the
diskette in
its
storage
envelope
whenever it is
not in one
of the
drives.
•
Do not
place a
diskette
in the
drive
while
you are
turning
the system
on or off.
•
Keep
diskettes
away
from
magnetic
fields
(transformers,
AC
motors, magnets,
tvs, radios,
etc.).
Strong
magnetic
fields
will erase
data
stored on a
diskette.
