Tests and Diagnostics
By repeating the decrease and increase of the LBA’s
address, this test continues to write the test data up to the
last address. After that, it reads out the data from the same
LBAs to compare.
If there are no 64 LBAs at last, this test is not executed for
the last address.
If any errors occur, this test displays the message “HDD
Write error “and writes the information to the text file
(errorlog.txt) as an error log.
Subtest 4 [Address Uniqueness Test]
This test writes the number of passes (UNIT32) (default is 0)
per LBA and the LBA number (UNIT32). To the rest of a LBA
(calculated as “LBA size - (UNIT32)*2”), it writes “0”.
This test writes the test data up to the last address. Then it
reads out the data to compare. The number of passes will be
0 (default value) unless comparing of the whole data is
completed. At the beginning of the test in the second round,
the number would become 1 (when Test Loop Yes is
selected. When Test Loop No is selected, the number will
not be changed. In that case, the number remains 0 at the
end of the test. ) If the test data and read data is not the
same, this test displays a message of “Data Compare error”
and writes the information to the text file (errorlog.txt) as an
error log.
(1 LBA (512-byte))
Subtest 5 [Specify Address Test]
First, specifying of the address of the start LBA, the data
length and test data for writing (Dword) is needed for this
test. Then this test writes the specified test data to the
specified address and read them to compare.
If any errors occur at comparing, this test displays the
message “Compare error“ and writes the information to the
text file (errorlog.txt) as an error log.
As for the details of the error log, refer to 3.12 Log utility.
