Atari 520ST

Most
disks
have a
small
write-protect
notch at
the
lower left-hand
corner
of the disk’s
plastic
casing.
Turning the
disk
over, you
will
see a
small, sliding tab.
To
write-protect a
disk,
slide
the tab so
that you
can see
through
the notch.
If
your disk does
not have a
write-protect
notch
visible on the
lower left-hand
corner,
you may
still be
able
to
write-protect
it. On
the
back of the
disk, there
should be a
sliding tab
in
the
lower
right-hand
corner. Push
the tab to
the
bottom
position to
write-
protect
the disk.
While write-protected,
a
disk cannot
be
formatted,
erased,
or
written to.
Of
course, you
can move
the
write-protect tab
back
to
the
unprotected
position
anytime you
wish to
record
information
on
the disk.
Commercial
program
disks do
not
usually
have
write-protect tabs.
These
disks are
permanently
write-protected as a
safety
precau-
tion. The TOS
System
disk you
received
with
the ST
System
is per-
manently
protected. You
cannot format,
erase, or
write
to
the
TOS
System disk.
Before duplicating a
disk
or copying
files
from
one disk to
another,
it is
recommended that you
write-protect
the
disk you are
duplicating or copying
files
from.
Doing
so
safeguards
you
against
mistakenly
inserting your
original
disk
when
the drive is'ready to
write
information on the
duplicate.
Such
confusion is
likely when
you are
using
a
single disk
drive
to
duplicate
disks
or
copy
files.
Caring
For Your
Microfloppy
Disks
Never place
disks
near any source
of
magnetism
(monitor,
television,
electric
motor, or
telephone).
Avoid
placing the
disks
near sources
of heat
and
moisture.
Never touch
or
clean the
surface of
the disk.
Never leave the
disks
in direct
sunlight.
