At Step 2, it writes the 512-byte data to the LBA decreased by 41 LBAs from the
LBA designated at the previous step.
At Step 3, it writes the 512-byte data to the LBA increased by 64 LBAs from the
LBA designated at the previous step.
At Step 4, it writes the 512-byte data to the LBA decreased by 41 LBAs from the
LBA designated at the previous step.
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.
