The information provided by the diagnostics tests includes: error code, system serial number, drive serial number, drive model, and drive firmware revision. Specific details of the drive failure are not included. When you run the diagnostics, the test results are stored in a log. After completing the test, you can print this log to a local printer or save it to a file.
