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.
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
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.
