Sequential read
This subtest performs forward reading of contents from track 0 to the
maximum track and then performs reverse reading of the contents from the
maximum track to track O.
Address uniqueness
This subtest writes the address data that is different sector by sector at each
track, then reads and compares it to the original data. This test is done for all
tracks.
There are three types ofreads as listed below.
• Forward sequential
• Reverse sequential
• Random
Random address/data
This subtest writes random data to random addresses (cylinder, head, and
sector), and then reads the data out and compares it to the original data.
Cross talk & peak shift
This subtest writes the eight types of worst Pattern data (shown below) to a
cylinder, then reads the data while shifting cylinder by cylinder.
Worst pattern data:
B5ADADh, 4A5252h, EB6DB6h, 149249h
63B63Bh, 9C49C4h, 2DB6DBh, D24924h
Write/read!compare( CE)
This subtest writes the B5ADADh worst pattern data to the CE cylinder, and
then reads the data out and compares it with the original data.
Write specified address
This subtest writes specified data to a specified cylinder and head.
