Problem
Suggested
Solution
The system
will
not boot from
the
hard
disk.
An
application
program
will
not
start
from the
hard
disk.
Run
the hard
disk
driver installation
program
HINSTALL.
If
the
problem
continues, the hard
disk should be backed up (see
Backing
Up
Data
in
Chapter
4)
and
reformatted (see
Formatting
in
Chapter
2).
The
program
contains garbled data
or
was
not
designed
to start
from
a hard
disk.
Try booting
from
the floppy drive with a
different
copy
of
the
program,
if it
still
won't
start
from
fhe
hard
disk,
contact the program's manufacturer
for
more
information.
If
you
still
have
problems, your hard
disk
may
have developed unusable
data.
Try erasing
individual
bad
files
and
replacing
them
with
valid
back-
ups.
If
this isn't
possible, follow these steps
to try
and
recover
data.
1.
Run
the
Markbad
option
of
the
HDX
program
on
the Atari
Hard
Disk
utilities
disk (as
described
in
Marking
Bad
Sectors
in
Chapter
4)
in
each
logical drive
containing unreadable
data.
Recover
as
much
data as
possible.
2.
Back
up
the
recovered
data
in
the
logical
drive
to
floppy
disks.
3.
Erase
all
data
in
the
problem
logical drive(s)
with
the Zero
option
of
the
HDX
program and
run
Markbad on
it
again.
4.
Copy
the data
you backed up
to
the
logical drive.
If
the
boot
partition (drive
C
on
physical
unit 0)
contains unreadable
data,
you
may
not
be
able
to
boot from
the
hard
disk.
Use
a
working
copy
of
the
Atari
Hard
Disk
Utilities
disk
to
boot
the
system and
follow the
steps
above.
To
make
the
partition
bootable
again,
install
the hard
disk driver
as described
in
Chapter
3.
If
necessary,
turn
to
Appendix
b
for
a
list
of error
messages and
suggested
solutions.
