Barracuda 18XL Product Manual, Rev. A 19
5.2.8.2.6 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 parame-
ter 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 completing the first two self-test segments, the drive will change the value in the Self-Test Results Value
field to Eh, update the log page in non-volatile memory with this new value, and begin the third self-test seg-
ment. Only the Self-Test Results Value field is changed as a result of this update.
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 zero, the drive passed with no errors detected by the DST. If the field is not zero, the test
failed for the reason reported in the field.
5.2.8.2.7 Self-Test Progress Indicator
Self-test progress is reported through the Request Sense command with the Self-Test Progress Indicator
(STPI) bit set.
5.2.8.2.8 Abort
There are several ways to abort a diagnostic. Power-on Reset and SCSI Reset are two mechanisms you can
use. You can also issue a Send Diagnostic command with an abort code in the function field to abort a cur-
rently-executing diagnostic. The log data will report an aborted command.
5.2.9 Product warranty
Beginning on the date of shipment to customer and continuing for a period of five years, Seagate warrants that
each product (including components and subassemblies) or spare part that fails to function properly under nor-
mal use due to defect in materials on workmanship or due to nonconformance to the applicable specifications
will be repaired or replaced, at Seagate’s option and at no charge to customer, if returned by customer at cus-
tomer’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 customer. For more detailed warranty information
refer to the Standard terms and conditions of Purchase for Seagate products.
Shipping
When transporting or shipping a drive, a Seagate approved container must be used. Keep your original box.
They are easily identified by the Seagate Approved Package label. Shipping a drive in a non-approved con-
tainer 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.
Product repair and return information
Seagate customer service centers are the only facilities authorized to service Seagate drives. Seagate does
not sanction any third-party repair facilities. Any unauthorized repair or tampering with the factory-seal voids
the warranty.
