6. The Hard Disk Test message will appear after a response to the Detail Status
prompt. Select a subtest to execute and press Enter. The following message
will appear during each subtest.
HARD DISK TEST XXXXXXX
SUB-TEST : XX
PASS COUNT: XXXXX ERROR COUNT: XXXXX
WRITE DATA: XX READ DATA : XX
ADDRESS : XXXXXX STATUS : XXX
The first three digits of the ADDRESS indicate the cylinder being tested, the
fourth digit the head, and the last two digits the sector.
The first digit of the STATUS number indicates the drive being tested and the
last two digits the error status code as explained in Table 3-3.
Subtest 01 Sequential Read
This subtest is a sequential reading of all HDD tracks starting at 0. When all
tracks have been read, the test starts at the last track and reads sequentially
back to track 0.
Subtest 02 Address Uniqueness
This subtest writes unique address data to each sector 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.
