When the following test is executed, the HDD data is
destroyed.
The display shown before executing write mode test
When executed, Data on hard disk will be destroyed.
Password ? [*****]
ESC : Exit
Before executing the write mode test, "When executed, Data on
hard disk will be destroyed." is displayed.
Password entry is urged. Only when the correct password is
entered, does the display go to the next one.
The correct password is "sharp" or "SHARP" in 5 digits. When typing
the correct password, the " * " is displayed. Instead of the character
content.
9) SEEK & WRITE/READ-VERIFY TEST
[Test conditions setting]
Similar to 4) SEEK & READ TEST. Cylinder range setting is 000 0
inmost cylinder 2.
1 Checking content
For the cylinder range and the sector range set in the above test, the
worst pattern data is written sequentially for every one track.
Then, the read/verify check is made for each track.
The number of the read/verify check is one.
(Test for 1 pass)
The write is made in the direction of 0 3 inmost cylinder.
The read/verify check is made in the direction of 0 3 inmost cylinder.
The write is made in the direction of inmost cylinder 3 0.
The read/verify check is made in the direction of inmost cylinder 3 0.
When writing data, write different data from the original stored data.
Before writing or reading, the head is moved to the previous or the
following cylinder.

(Head movement)
When track N is read, the head moves as follows. (The head arm is
deflected back and forth.)

Reading is made at 2. and 4.
(Worst pattern data)
There are two kinds of worst data: B6DBH and 6DB6.
In case of an error during the above test, a retry is repeated up to
the set number of retries. Every time an error occurs a retry is per-
formed up to the set number of retries and, error logging is made.
Logging is made for HD and DRAM.
When the "Error Stop" is set in the test condition setting, if an error
occurs during the above test, the error display is shown and the test
is interrupted. Press the space key to resume the test.
When the "Continue" is set, even if an error occurs, the error display
is made but the test is not stopped.
When "1 Pass" is set, a series of tests is made only once.
