Subtest 01
Sequential read
The sequential read test is a sequential reading of the 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.
Subtest 02
Address uniquence (uniqueness)
The address uniqueness test writes unique address data to each sector, track by track,
on the HDD. The data written to each sector is then read and compared with the
original data. There are three ways in which the HDD can be read:
·
Forward sequential
·
Reverse sequential
·
Random
Subtest 03
Random address/data
This subtest writes random data to random addresses to the cylinder, head, and
sector on the HDD and then reads the written data back and compares it to the
original data.
Subtest 04
Cross talk & peek (peak) shift
This subtest writes the eight types of worst pattern data (shown below) to a cylinder,
then reads the data while moving from cylinder to cylinder.
Worst pattern data:
B5ADADh, 4A5252h, EB6DB6h, 149249h
63B63Bh, 9C49C4h, 2DB6DBh, D24924h
Subtest 05
Write/read/compare(CE)
This subtest writes the worst pattern data (B5ADADh) to the CE cylinder, and then
reads the data out and compares it with the original data.
Subtest 06
Write specified address
