[Read mode test]
(1) Drive status display
The following standard values of hard disk drive are displayed:
(2) Sequential seek test
[Test condition setting]
• LBA range (0 ~ final cylinder)
The LBA range for test is set.
• Retry count (0 ~ 4)
The number of retry in case of an error is set.
• Error stop/Continue/1 pass
In case of an error, selection is made whether interrupt is made or not.
Also used to select whether the test is executed or not by 1 pass.
Also used to select whether the test is executed or not by 1 pass.
• Test start? (Yes/No)
Used to select whether the test is executed or not.
[Test contents]
Sequential seek is executed in the LBA range set in the above proce-
dure. (In the sequence of 0

Final cylinder). When the seek test of the
set range is completed, it is considered as 1 pass. When an error
occurs during the above test, retry is repeated by the set number of
retry. If an error still occurs after completion of retry by the set n umber
of retry, error logging is made to the HD and the DRAM.
When "Error stop" is set in the test condition setting, if an error occurs
during the above test, the error display is interrupted. To resume the
test, press [SPACE] key.
When "Continue" is set, if an error occurs, the operation is not inter-
rupted though the error display is made.

When "Error stop" is set in the test condition setting, if an error occurs
during the above test, the error display is interrupted. To resume the
test, press [SPACE] key.
When "Continue" is set, if an error occurs, the operation is not inter-
rupted though the error display is made.
When "1 Pass" is set, a series of tests is executed only once.
(3) Seek & read test
[Test conditions setting]
Similar to the above (2). The following setting must be additionally per-
formed. Sector count (0 ~ Final sector)
The number of sectors to be read for one operation.
formed. Sector count (0 ~ Final sector)
The number of sectors to be read for one operation.
[Test contents]
Sequential read is executed for every sector in the LBA range set by the
above procedure. (In the direction of 3 ~ Final cylinder)
When the write/read test in the set range is completed, it is considered
as 1 pass.
Before execution of read, however, seek is made to the previous LBA
and the next LBA.

[Head movement]
When reading an LBA (N), the head moves as follows:

When an error occurs during the above test, retry is repeated by the set
retry number. If an error still occurs after completion of retry by the set
retry number. If an error still occurs after completion of retry by the set
retry number, error logging is made to the DRAM.
When "Error Stop" is set in the test condition setting, if an error occurs
in the above test execution, the error display is interrupted. To resume
in the above test execution, the error display is interrupted. To resume
the test, press [SPACE] key.
When "Continue" is set, if an error occurs, the operation is not inter-
rupted though the error display is made.

by the set n umber of retry, error logging is made to the DRAM.
When "Error stop" is set in the test condition setting, if an error occurs
