APPENDIX A
TROUBLESHOOTING AND
PREVENTIVE MAINTENANCE
Troubleshooting
The most
common
and
easily fixed
hard
disk
problem
is
a
loose cable
connection
or failure
to
switch
on
the
power
to
the
disk
drive.
Always
check
these
first
before exploring other
possibilities.
One
instance
where
this
will
be
a
problem
is
when
you
are using the
HDX
program.
If
the
drive
isn't
properly
connected,
you
will
not
be
able
to
complete
your
HDX
operation
because
the physical
unit
will
not
be
shadowed and
available
for
selection.
If
you
run
into
problems
connecting
or
operating your
MEGAFILE
hard
disk
drive,
check
the following
list
for
suggested
solutions.
Suggested
Problem
Solution
Power
light
does
not
come
on.
Drive doesn't whir
and busy
light
doesn't
come
on.
Hard
disk icon
C
does
not
appear
when
you
switch
on
your system.
Make
sure
the
power
cable
is
securely con-
nected on both
ends and
the
electrical outlet
is
working
properly.
Make
sure
all
hard
disk
cables are
secure
and
the
hard
disk
is
switched
on.
If
you
are
booting
from a
floppy
disk,
make
sure
you have
a working
floppy disk
in
drive
A.
If
the
problem
persists,
take the hard
disk
in for
servicing.
Make
sure
the
hard
disk
is
properly
connected
and
switched
on.
If
you
are booting from a
floppy
drive,
make
sure
the
boot
disk
contains
AHDI.PRG
in
the
AUTO
folder.
If
you
are
booting
from
the
hard
disk,
you
may
need
to
back up
your data (see
Backing
Up
Data
in
Chapter
4)
and
reformat
the drive
(see
Formatting
in
Chapter
2).
