(a.2) Specification of Range
of
Cylinders
to
Be
Tested
Cylinder scope I
[01
<->391
=
t>lt>l
-
t>lt>l
Specify the range (scope) of
the
cylinder
to
be
tested by
entering the first cylinder number
and
the last cylinder
number. For example, when entering
"10
- 12" if the test
disk
is
the
09
sectors/track format,
the
test range from
10.0.01 to 12.1.09 isspecified.
When entering both
cylinder number are
[[.all
only or
[[all
+
[[.all,
the
entire'range
of
cylinders
is
specified.
In
this case, if a
09
sectorsltrack format disk
is
used,
cylinders from 00.1.01
to
39.1.09 are specified.
(a.3) Specification
of
Counting Sectors
Specify
the number
of
counting sectors capable
of
being
processed
by
one instruction.
This counting value depends on the disk format for use. For
example, when a
09
sectors/track format disk
is
used,
Sector cau nt?
[1,3,
91
~
t>l
When a
08
sectors/track format disk
is
used, the system
displays the following inquiry.
"[1,2,4,81
= t>l"
If
other value which
is
not displayed
is
entered,
the
system
does
not
accept such a value and
req~ires
proper data entry
once
again.
When pressing
[[all
+
[[.a
II
or only [[
.all,
assuming
that the maximum value
of
the sector
count
is
specified,
the system executes the following program.
(b) Test
(b.l)
Specification of Number of Times Retry
Retry
count?
[0 < -
>41
=
t>l
Specify
the number
of
times retry.
When the system reads data from
the
disk, if it
detects
an
error, it tries
to
perform the same operation for the number
of
times
specified.
(b.2) Specification of Error Stop
Error
stop?
[0:
Yes,
1: Nol =
t>l
If
an error occurs while condUcting the
test,
specify wheth-
er
to
abort or continue the test.

(b,3) Confirmation

[0: Yes, 1: Nol

test
or
not.

When
entering
[[111,
control exits
to
(a.l) "Specification
of Test Drive mentioned in (a.l
)".
On
the
other hand, when
entering
[[all,
the
system displays
the
screen
as
shown
in
Figure FDD-3 and starts
the
test.
The lower left screen
shows
the
number
of
times
test
pass
and physical address
[[TTHSSI;
the
lower right screen
shows the test
mode.
(Note
that
the
number
of
times test
pass
is
denoted
in
hexadecimal
notation
and
the
physical
address
in
decimal notation.)

In
addition, the right end
of
the
screen shows
the
number
of
occurrences
of
errors
in
each
type.
(The number
of
ocCUrrences
of
errors
is
also
denoted
in
hexadecimal
notation.)
IbA) Abortion and Completion
of
Test
By
pressing [[ESCII while
the
system executes the test,
control
exits to
the
FDD
test
menu (Figure FDD-1); by
pressing
[[F21I,
the
system displays
the
following message
on the lower left screen and
stops
the
test.
"Test stopped by user."
At the time, by pressing
[[Flll,
the system continues
the
test. Whereas,
by
pressing
[[ESCII,
control exits
the
FDD.
test menu (Figure
FDD·l).
(c)
Error
Processing
If
the system detects
an
error after it
conducts
the test until
it starts the seek operation, it
stops
the
test
irrespective
of
"Yes"
Or
"No"
of the error stop described
in
(b.2). At the
time, when pressing
[[ESCII,
control exits
to
the FDD test
menu (Figure
FDD·l).
If
the system
detects
an error while it
conducts
the read
check test,
it
displays the
command
parameter and status
where
the
error occurs (Figure FDD-4) and increments
the
right-hand error counter.
If
the
Error
Stop
is
set
to
"No",
the system updates the error
counter
every
time
an
error
occurs and continues the
test
(the
syst~m
only
displays
the
newest error information).
On the other hand, while
the
error
stop
is
set
to
"Yes",
the
system stops the
test
if an error occurs.
At
the
time,
when
pressing
I[
~)],
the system
continues
to
conduct
the
test. Whereas, when pressing
[[ESCII,
control exits
to
the
FDD
test menu (Figure FDD-l).
For details
of
error messages, see paragraph (3).
