[Test contents]

The sequential read test for every one track is executed in the range set
as above.

Completion of the read test in the set range is counted as 1 pass.

The operation of this test is as shown below:

[Test condition setting]

Similar to the above (2). However, the cylinder set range is 01

0

79.

[Test contents]

The worst pattern data are written into each track in all the set range.
Then perform the read/verify check. When the write/read test in the set

range in the direction of 0

0

79 cylinder is completed, it is considered

as 1 pass.
The operation of this test is as shown below:

When writing data, write different data from those originally stored.

(Worst pattern data)
Word data: There are two kinds of data: B6DBh, 6DB6h.

[Test condition setting]

Similar to the above (2). However, setting of the retry number is omitted.

[Test contents]

The write/read test in the set range is executed.
When the write/read test in the set range is completed, it is considered
as 1 pass.
The operation of this test is as shown below:

The error contents generated in procedures (1) ~ (4) are displayed for
each test item. The display items are test item, test condition, drive, cyl-
inder, head, sector, error contents, and hour/minute/second. The maxi-
mum number of display items is 50 for each test.

On the above menu, use [

2

] and [

4

] keys to select a test item. Press

[ENTER] key to execute the test. When [ESC] key is pressed, the dis-

play returns to the initial menu.

Select an item in each position indicated with "

"

(In the above display, the item surrounded by a 

 is selected and the

value surrounded by a 

is selected.)

When, in the above display, "Pass count" is counted up (when the test

point is counted from 00.0.01 to 79.1.10, Pass count is counted up by 1)

and all the error counters of all the error kinds are not counted up
(remaining at 00000), the test is OK.

During execution of the test, when [SPACE] key is pressed, the test is

interrupted. 

During interruption of the test, when [SPACE] key is pressed, the test is

resumed. 

During execution or interruption of the test, when [ESC] key is pressed,
the display returns to the menu of (1).
