3 Tests and Diagnostics | 3.9 Hard Disk Test | |
Subtest 01 | Sequential read |
|
| This subtest is a sequential reading of all the tracks on the HDD starting at track 0 | |
| to maximum track. 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 uniqueness |
|
| This subtest writes unique address data to each sector of the HDD | |
| The data written to each sector is then read and compared with the original data. | |
| There are three ways the HDD can be read: |
|
1.Forward sequential 2.Reverse sequential 3.Random
Subtest 03 Random address/data
This subtest writes random data in a random length to random addresses. This data is then read and compared to the original data.
