If the drive receives a START STOP UNIT command with the START bit equal to 0 before receiving a NOTIFY (ENABLE SPINUP) primitive, the drive waits for a START STOP UNIT command with the START bit equal to 1. After receiving a START STOP UNIT command with the START bit equal to 1, the drive waits for a NOTIFY (ENABLE SPINUP) primitive. -

Reliability specifications The following reliability specifications assume correct host and drive operational interface, including all inter- face timings, power supply voltages, environmental requirements and drive mounting constraints. Seek error rate: Less than 10 errors in 10 seeks Read Error Rates Recovered Data Less than 10 errors in 10 bits transferred (OEM default settings) -
Page 18: Seek Errors
6.1.3 Seek errors A seek error is defined as a failure of the drive to position the heads to the addressed track. After detecting an initial seek error, the drive automatically performs an error recovery process. If the error recovery process fails, a seek positioning error (Error code = 15h or 02h) will be reported with a Hardware error (04h) in the Sense Key. -

There will not be any discrete tones more than 10 dB above the masking noise on typical drives when mea- sured according to Seagate specification 30553-001. There will not be any tones more than 24 dB above the masking noise on any drive. -
Page 41: Corrosive Environment
The sil- ver, copper, nickel and gold films used in Seagate products are especially sensitive to the presence of sulfide, chloride, and nitrate contaminants. Sulfur is found to be the most damaging. In addition, electronic components should never be exposed to condensing water on the surface of the printed circuit board assembly (PCBA) or exposed to an ambient relative humidity greater than 95%. -

Page 43: Defect And Error Management
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). - Page 44 The drive firmware error recovery algorithms consists of 13 levels for read recoveries and five levels for write. Each level may consist of multiple steps, where a step is defined as a recovery function involving a single re- read or re-write attempt. The maximum level used by the drive in LBA recovery is determined by the read and write retry counts.
-
Page 45: Sas System Errors
SAS system errors Information on the reporting of operational errors or faults across the interface is given in the SAS Interface Manual. The SSP Response returns information to the host about numerous kinds of errors or faults. The Receive Diagnostic Results reports the results of diagnostic operations performed by the drive. Status returned by the drive to the initiator is described in the SAS Interface Manual. -
Page 46: Deferred Auto-Reallocation
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 47: Installation
Installation Cheetah 15K.6 disk drive installation is a plug-and-play process. There are no jumpers, switches, or termina- tors on the drive. SAS drives are designed to be used in a host system that provides a SAS-compatible backplane with bays designed to accommodate the drive. In such systems, the host system typically provides a carrier or tray into which you need to mount the drive. - Page 48 If forced air is determined to be necessary, possible air-flow patterns are shown in Figure 13. The air-flow pat- terns are created by one or more fans, either forcing or drawing air as shown in the illustrations. Conduction, convection, or other forced air-flow patterns are acceptable as long as the temperature measurement guide- lines of Section 7.4.1 are met.
-
Page 49: Drive Mounting
Drive mounting Mount the drive using the bottom or side mounting holes. If you mount the drive using the bottom holes, ensure that you do not physically distort the drive by attempting to mount it on a stiff, non-flat surface. The allowable mounting surface stiffness is 80 lb/in (14.0 N/mm). -
