The first digit of the STATUS number indicates the drive being tested, and the
last two digits indicate the error status code as explained in Table 3-3.
Subtest 01 Sequential Read
This subtest is a sequential reading of all the tracks on the HDD starting at
track 0. When all the tracks have been read, the test starts at the maximum
track and reads the tracks sequentially back to track 0.
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
• Random
Subtest 03 Random Address/Data
This subtest writes random data to random addresses on the HDD cylinder,
head and sector. This data is then read and compared to the original data.
