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.
