Subtest 3 [Address Jump Test]
This test writes the test data (AAAAAAAAh) to
1. LBA 63 (by 512-byte)
2. LBA 22 (=63 - 41) (by 512-byte)
3. LBA 86 (=22 + 64) (by 512-byte)
4. LBA 45 (=86 - 41) (by 512-byte)
At Step 1, this test starts from the LBA 63 and writes the test
data by 512-byte.
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”.
