Description
of
the
error.
Note:
See
for
error
code
listings.
Fixed
disk
advanced
test
(FDAT)
PC-Doctor’s
(PCDR)
Fixed-Disk
Advanced
Test
module
(FDAT)
is
a
full-featured
highly
configurable
fixed-disk
test
suite.
The
configurable
capabilities
of
FDAT
allow
users
to
enable
or
disable
specific
tests,
enable
or
disable
testing
features,
control
the
test
log
detail,
alter
testing
parameters,
etc.
FDAT
will
test
for
and
report
most
commonly
found
errors
on
a
fixed-disk
drive
and
is
able
to
test
up
to
128
SCSI
and
4
IDE
drives
(up
to
132
total
drives).
Drive
information
is
gathered
through
FDAT’s
enumeration
of
available
devices
and
user
specific
configuration
parameters
located
in
the
FDAT.INI.
FDAT
uses
information
supplied
by
these
features
to
indicate
specifically
what
devices
are
available
for
test,
what
tests
are
available
for
the
device,
device
properties,
etc.
Modify
the
FDAT.INI
file
in
PC
Doctor
for
DOS
to
change
testing
parameters.
FDAT
consists
of
the
following
subtests
and
features.

supported
log
of
errors
on
the
drive.
Multitasking:
To
allow
simultaneous
testing
of
multiple
hard
drives
whenever
possible,
the
FDAT
module
is
written
as
a
set
of
multitasking
functions.
Each
drive
under
test
can
run
the
same
test
or
run
a
different
test
at
the
same
time.
Each
subtest
is
written
to
handle
a
single
test
pass
and
all
test
variables
are
kept
track
of
in
a
Chapter
4.
