5.3.6Drive Self Test (DST)

Drive Self Test (DST) is a technology designed to recognize drive fault conditions that qualify the drive as a failed unit. DST validates the functionality of the drive at a system level.

There are two test coverage options implemented in DST:

1.Extended test

2.Short test

The most thorough option is the extended test that performs various tests on the drive and scans every logical block address (LBA) of the drive. The short test is time-restricted and limited in length—it does not scan the entire media contents, but does some fundamental tests and scans portions of the media.

If DST encounters an error during either of these tests, it reports a "diagnostic failed" condition. If the drive fails the test, remove it from service and return it to Seagate for service.

5.3.6.1DST failure definition

The drive will present a “diagnostic failed” condition through the self-tests results value of the diagnostic log page if a functional failure is encountered during DST. The drive parameters are not modified to test the drive more stringently, and the recovery capabilities are not reduced. All retries and recovery processes are enabled during the test. If data is recoverable, no failure condition will be reported regardless of the recovery processes required to recover the data.

The following conditions are considered DST failure conditions:

•Read error after recovery attempts are exhausted

•Write error after recovery attempts are exhausted

Recovered errors will not be reported as diagnostic failures.

5.3.6.2Implementation

This section provides all of the information necessary to implement the DST function on this drive.

5.3.6.2.1State of the drive prior to testing

The drive must be in a ready state before issuing the SEND DIAGNOSTIC command. There are multiple reasons why a drive may not be ready, some of which are valid conditions, and not errors. For example, a drive may be in process of doing a FORMAT UNIT, or another DST. It is the responsibility of the host application to determine the “not ready” cause.

5.3.6.2.2Invoking DST

To invoke DST, submit the SEND DIAGNOSTIC command with the appropriate Function Code (001b for the short test or 010b for the extended test) in bytes 1, bits 5, 6, and 7.

5.3.6.2.3Short and extended tests

DST has two testing options:

1.short

2.extended

These testing options are described in the following two subsections.

Each test consists of two segments: an electrical test segment and a read/verify scan segment.

Short test (Function Code: 001b)

The purpose of the short test is to provide a time-limited test that tests as much of the drive as possible within 120 seconds. The short test does not scan the entire media contents, but does some fundamental tests and scans portions of the media. A complete read/verify scan is not performed and only factual failures will report a "diagnostic failed" condition. This option provides a quick confidence test of the drive.
