Subtest 01 

Sequential read 

This subtest reads sequentially all the track data on the HDD starting at track 
0 (forward reading). When all the tracks on the HDD have been read, the test 
reads the maximum track data and continuous to read the track data on the 
HDD sequentially back to track 0 (reverse read). 

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: 

•  Forward sequential 
•  Reverse sequential 
•  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.
