Subtest 01 
Sequential read 
This subtest is a sequential reading of all the tracks on the HDD starting at track 0. 
When all the tracks on the HDD have been read, the test starts at the maximum 
track and reads the tracks on the HDD sequentially back to track 0. 
Subtest 02 
Address uniqueness 
This subtest writes unique address data to each sector of the HDD track-by-track. 
The data written to each sector is then read and compared with the original data. 
There are three ways the HDD can be read: 
1.  Forward sequential 
2.  Reverse sequential 
3.  Random 
Subtest 03 
Random address/data 
This subtest writes random data in a random length to random addresses. This data 
is then read and compared to the original data.
