When addressing these drives in LBA mode, all blocks (sectors) are consecutively numbered from 0 to n–1, where n is the 

number of guaranteed sectors as defined above.
Refer to 

 on page 15 (words 60-61 and 100-103) for additional information about 48-bit 

addressing support of drives with capacities over 137 GB.

Rated workload

Average rate of <55TB/year. The MTBF specification for the drive assumes the I/O workload 

does not exceed the average annualized workload rate limit of 55TB/year. Workloads exceed-

ing the annualized rate may degrade the drive MTBF and impact product reliability. The 

average annualized workload rate limit is in units of TB per year, or TB per 8760 power-on 

hours. Workload rate limit = TB transferred × (8760/recorded power-on hours).

Warranty

To determine the warranty for a specific drive, use a web browser to access the following web 

page: 

http://www.seagate.com/support/warranty-and-replacements/

From this page, click on “Check to see if the drive is under Warranty”. Users will be asked to 
provide the drive serial number, model number (or part number) and country of purchase. The
