Log page entries

When the drive begins DST, it creates a new entry in the Self-test Results Log page. The new entry is created

by inserting a new self-test parameter block at the beginning of the self-test results log parameter section of the

log page. Existing data will be moved to make room for the new parameter block. The drive reports 20 param-

eter blocks in the log page. If there are more than 20 parameter blocks, the least recent parameter block will be

deleted. The new parameter block will be initialized as follows:

1.

The Function Code field is set to the same value as sent in the DST command

2.

The Self-Test Results Value field is set to Fh

3.

The drive will store the log page to non-volatile memory

After a self-test is complete or has been aborted, the drive updates the Self-Test Results Value field in its Self-

Test Results Log page in non-volatile memory. The host may use Log Sense to read the results from up to the

last 20 self-tests performed by the drive. The self-test results value is a 4-bit field that reports the results of the

test. If the field is set to zero, the drive passed with no errors detected by the DST. If the field is not set to zero,

the test failed for the reason reported in the field.

The drive will report the failure condition and LBA (if applicable) in the Self-test Results Log parameter. The

Sense key, ASC, ASCQ, and FRU are used to report the failure condition.

5.2.6.2.5

Abort

There are several ways to abort a diagnostic. You can use a SCSI Bus Reset or a Bus Device Reset message

to abort the diagnostic.

You can abort a DST executing in background mode by using the abort code in the DST Function Code field.

This will cause a 01 (self-test aborted by the application client) code to appear in the self-test results values

log. All other abort mechanisms will be reported as a 02 (self-test routine was interrupted by a reset condition).

5.2.7

Product warranty

Beginning on the date of shipment to the customer and continuing for the period specified in your purchase

contract, Seagate warrants that each product (including components and subassemblies) that fails to function

properly under normal use due to defect in materials or workmanship or due to nonconformance to the applica-

ble specifications will be repaired or replaced, at Seagate’s option and at no charge to the customer, if returned

by customer at customer’s expense to Seagate’s designated facility in accordance with Seagate’s warranty

procedure. Seagate will pay for transporting the repair or replacement item to the customer. For more detailed

warranty information, refer to the standard terms and conditions of purchase for Seagate products on your pur-

chase documentation.

The remaining warranty for a particular drive can be determined by calling Seagate Customer Service at

1-800-468-3472. You can also determine remaining warranty using the Seagate web site (www.seagate.com).

The drive serial number is required to determine remaining warranty information.

Shipping

When transporting or shipping a drive, use only a Seagate-approved container. Keep your original box.

Seagate approved containers are easily identified by the Seagate Approved Package label. Shipping a drive in

a non-approved container voids the drive warranty.

Seagate repair centers may refuse receipt of components improperly packaged or obviously damaged in tran-

sit. Contact your authorized Seagate distributor to purchase additional boxes. Seagate recommends shipping

by an air-ride carrier experienced in handling computer equipment.
