(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.
-17-
(b,3) Confirmation of Test Execution
Test start? [0: Yes, 1: Nol
~
t>l
Confirm whether to execute the 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.)
Pass N [Oxl
=
t>lt>lt>lt>l
THSS
~
t>lt>lt>lt>lt>l
Test mode: Read Test drive: Drive A
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).
