Seagate products must comply with the “Marking of presence” requirements in Section 5 of CNS 15663, effective January 1, 2018. This product is Taiwan RoHS compliant. -
Page 14: General Description
The drives also use a high-performance actuator assembly with a low-inertia, balanced, patented, straight arm design that provides excellent performance with minimal power dissipation. Seagate recommends validating the configuration with the selected HBA/RAID controller Note manufacturer to ensure use of full capacity is supported. -

Page 16: Formatted Capacities
Users having the necessary equipment may modify the data block size before issuing a format command and obtain different formatted capacities than those listed. To provide a stable target capacity environment and at the same time provide users with flexibility if they choose, Seagate recommends product planning in one of two modes: Seagate designs specify capacity points at certain block sizes that Seagate guarantees current and future products will meet. -

Page 19: Cache Operation
When prefetch (read look-ahead) is enabled (enabled by DRA = 0), the drive enables prefetch of contiguous blocks from the disk when it senses that a prefetch hit will likely occur. The drive disables prefetch when it decides that a prefetch hit is not likely to occur. Seagate Exos X12 SAS Product Manual, Rev. C... -

An interface error is defined as a failure of the receiver on a port to recover the data as transmitted by the device port connected to the receiver. The error may be detected as a running disparity error, illegal code, loss of word sync, or CRC error. Seagate Exos X12 SAS Product Manual, Rev. C... -

Page 36: About Self-Encrypting Drives
The Trusted Computing Group (TCG) is an organization sponsored and operated by companies in the computer, storage and digital communications industry. Seagate’s SED models comply with the standards published by the TCG.

Page 37: Data Bands
In addition to providing a locking mechanism to prevent unwanted firmware download attempts, the drive also only accepts download files which have been cryptographically signed by the appropriate Seagate Design Center. Three conditions must be met before the drive will allow the download operation: The download must be an SED file. -
Page 38: Defect And Error Management
SCSI defect and error management involves drive internal defect/error management and SAS system error considerations (errors in communications between the initiator and the drive). In addition, Seagate provides the following technologies used to increase data integrity and drive reliability: •... -
Page 39: Sas System Errors
This is in contrast to the system having to use the Reassign Command to reassign a location that was unreadable and then generate a write command to rewrite the data. DAR is most effective when AWRE and ARRE are enabled—this is the default setting from the Seagate factory. With AWRE and ARRE disabled DAR is unable to reallocate the failing location and will report an error sense code indicating that a write command is being attempted to a previously failing location. -
Page 40: Protection Information (Pi)
RDPROTECT and WRTPROTECT fields. The drive will generate 8 bytes (e.g.0xFFFF) 8 bytes of Protection Information to be stored on the media, but the 8 bytes will not be transferred to the host during a read command. Type 3 - Seagate products do not support Type 3. 8.6.2 Setting and determining the current Type Level A drive is initialized to a type of PI by using the format command on a PI capable drive. -
