DISK
SYSTEM
•
Handle diskettes
by the
jacket
only. Do
not
touch
any of
the
exposed
surfaces.
Don't try
to
wipe
or clean
the
diskette
surface; it
scratches
easily.
•
Keep
diskettes out
of direct
sunlight
and away
from
heat.
•
Avoid
contamination of
diskettes
with
cigarette
ashes,
dust or
other
particles.
•
Do not write
directly on the
diskette
jacket with
a hard
point device
such
as a
ball point
pen or lead
pencil;
use a felt
tip
pen only.
•
Store diskettes
in a vertical
file
folder
on a
shelf
where
they are
protected
from
pressure
to their sides
(just
as phono
records
are
stored).
•
In
very
dusty environments,
you may
need
to provide
filtered
air to the
computer
room.
Tips on
Labeling
Diskettes
Each diskette
has
a permanent
label
on its
jacket.
This label
is for
"vital
statistics"
that will never
change.
For
example,
to help
keep
track
of diskettes.
it's
a good idea
to assign
a unique
number
to
each diskette.
Write
such
a number
on the
permanent label.
You
might
also
put your
name
on
the diskette,
and
record
the date when
the diskette
was
first
put into
use.
Remember,
use
only
a
felt
tip pen for
marking.
This "permanent"
label
is not
a
good place
to record
the contents
of the
diskette
since
that will change,
and
you don't
want
to
be erasing
or
scratching
out
information
from this label.

the following:
•
Are
you using
a trsdos
"system"
diskette?

Is
the diskette
properly inserted
into Drive

•
If
external
drives
are present,
are
