Subtest 1
[Sequential Read Test]
This test reads out the whole data from the address of LBA 0
to the last. The data is read by 64-LBA unit.
If any errors occur, this test displays the message “HDD
Read error “and writes the information to the text file
(errorlog.txt) as an error log.
Subtest 2
[Partial Read Test]
This test reads the data from the top and middle of the HDD
area by 1GB. It reads also from 1GB area before of the last
address to the last.

Read error “and writes the information to the text file
(errorlog.txt) as an error log.
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
