written to each sector is then read and compared with the original data. There are three ways
the HDD can be read.

3) 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.
4) Cross talk & peak shift
This subtest writes eight types of worst pattern data (listed below) to a cylinder, then reads
the data while moving from cylinder to cylinder. (Test the data interference in the neighbor
track)
