Subtest 01
Sequential read

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
•

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.
