  • Page 8: Scope

    LLC, Cheetah SAS (Serial Attached SCSI) disk drives. Cheetah 15K.7 drives support the SAS Protocol specifications to the extent described in this manual. The SAS Interface Manual (part number 100293071) describes the general SAS characteristics of Cheetah 15K.7 and other Seagate SAS drives. The Self-Encrypting Drive (SED) Users Guide, part number 100515636 describes the interface, general operation and security features available on SED drives.

  • Page 9: Standards, Compliance And Reference Documents

    Section 11.3. Standards The Cheetah 15K.7 SAS family complies with Seagate standards as noted in the appropriate sections of this manual and the Seagate SAS Interface Manual, part number 100293071. The drives are recognized in accordance with UL 60950-1 and CSA 60950-1 as tested by UL and EN60950-1 as tested by TUV.

  • Page 11: Reference Documents

    Seagate also has internal systems in place to ensure ongoing compliance with the RoHS Directive and all laws and regulations which restrict chemical content in electronic products. These systems include standard operat- ing procedures that ensure that restricted substances are not utilized in our manufacturing operations, labora- tory analytical validation testing, and an internal auditing process to ensure that all standard operating procedures are complied with.

  • Page 12: General Description

    Opening the HDA for any reason voids your warranty. Cheetah 15K.7 drives use a dedicated landing zone at the innermost radius of the media to eliminate the pos- sibility of destroying or degrading data by landing in the data zone. The heads automatically go to the landing zone when power is removed from the drive.

  • Page 14: Reliability

    Seagate designs specify capacity points at certain block sizes that Seagate guarantees current and future products will meet. We recommend customers use this capacity in their project planning, as it ensures a stable operating point with backward and forward compatibility from generation to generation.

  • Page 45: Defect And Error Management

    10.0 Defect and error management Seagate continues to use innovative technologies to manage defects and errors. These technologies are designed to increase data integrity, perform drive self-maintenance, and validate proper drive operation. 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).

    On regular duty drives, if the host system makes use of the BMS Log Page, it can avoid placing data in suspect locations on the media. Unreadable and recovered error sites will be logged or reallocated per ARRE/AWRE settings. Cheetah 15K.7 SAS Product Manual, Rev. C...

  • Page 48: Media Pre-Scan

    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.
