This test performs forward reading of contents from track
0 to track 610 and then performs reverse reading of the
contents from track 610 to track 0.
Subtest 02
Address
This test writes the address data(sector by sector) track
by track, then reads the data and compares it to the
original data.
Following three kinds of read operations are performed.
(Forward sequential, Reverse sequential,
Subtest 03
Random address/data (Execution time 48 seconds)
This test write random data in random units to random
address (cylinder, head, sector) and then reads the data
out and compares it to the original data.
Subtest 04
Cross talk & peak shift (Execution time: 30 seconds)
This test writes the eight types of worst pattern data
(shown below) to cylinders then reads the data while
shifting cylinder by cylinder.
