When referring to drive capacity one gigabyte or GB equals one billion bytes and one terabyte or TB equals one trillion bytes Your computer s operating system may use a different standard of measurement and report a lower capacity In addition some of the listed capacity is used for formatting and other functions and thus will not be available for data storage Actual quantities will vary based on various factors including file size file format features and application software Actual data rates may vary depending on operating environment and other factors The export or re export of hardware or software containing encryption may be regulated by the U S Department of Commerce Bureau of Industry and Security for more information visit www bis doc gov and controlled for import and use outside of the U S Seagate reserves the right to change without notice product offerings or specifications Contents Seagate Technology Support Services 1 1 0 chm 2 2 0 Applicable standards and reference documentation 3 2 1 Standards oee rc CITED 3 2 1 1 Electromagnetic compatibility llle 3 2 1 2 Electromagnetic compliance 1 4 2 1 3 European Union Restriction of Hazardous Substances RoHS 5 2 1 4 China Restriction of Hazardous Substances RoHS Directive 5 2 2 Reference

As with a non SED drive the download file must pass the acceptance criteria for the drive For example it must be appli cable to the correct drive model and have compatible revision and customer status 8 8 POWER REQUIREMENTS The standard drive models and the SED drive models have identical hardware however the security and encryption portion of the drive controller ASIC is enabled and functional in the SED models This represents a small additional drain on the 5V supply of about 30mA and a commensurate increase of about 150mW in power consumption There is no additional drain on the 12V supply See the tables in Section 6 3 for power requirements on the standard non SED drive models 8 9 SUPPORTED COMMANDS The SED models support the following two commands in addition to the commands supported by the standard non SED models as listed in Table 8 Security Protocol Out B5h Security Protocol In A2h 8 10 SANITIZE CRYPTOGRAPHIC ERASE This command cryptographically erases all user data on the drive by destroying the current data encryption key and replacing it with a new data encryption key randomly generated by the drive Sanitize CRYPTOGRAPHIC ERASE is a SCSI CDB Op code 48h and selecting the service action code 3 CRYPTOGRAPHIC ERASE 8 11 REVERTSP SED models will support the RevertSP feature which erases all data in all bands on the device and returns the contents of all SPs Security Providers on the device to their ori

BMS interrupts immediately to service host commands from the interface bus while performing reads BMS will complete any BMS initiated error recovery prior to returning to service host initiated commands Overhead associated with a return to host servicing activity from BMS only impacts the first command that interrupted BMS this results in a typical delay of about 1 ms 9 5 MEDIA PRE SCAN Media Pre Scan is a feature that allows the drive to repair media errors that would otherwise have been found by the host system during critical data accesses early in the drive s life The default setting for Media Pre Scan is enabled on standard products Media Pre Scan checks each write command to determine if the destination LBAs have been scanned by BMS If the LBAs have been verified the drive proceeds with the normal write command If the LBAs have not been verified by BMS Pre Scan will convert the write to a write verify to certify that the data was properly written to the disk During Pre Scan write verify commands write performance may decrease by 50 until Pre Scan completes Write performance testing should be performed after Pre Scan is complete This may be checked by reading the BMS status To expedite the scan of the full pack and subsequently exit from the Pre Scan period BMS will begin scanning immediately when the drive goes to idle during the Pre Scan period In the event that the drive is in a high transaction traffic environment and is un

This counter is referred to as the Failure Counter Error rate is the number of errors per operation The algorithm that S M A R T uses to record rates of error is to set thresholds for the number of errors and their interval If the number of errors exceeds the threshold before the interval expires the error rate is considered to be unacceptable If the number of errors does not exceed the threshold before the interval expires the error rate is considered to be acceptable In either case the interval and failure counters are reset and the process starts over Predictive failures S M A R T signals predictive failures when the drive is performing unacceptably for a period of time The firmware keeps a running count of the number of times the error rate for each attribute is unacceptable To accomplish this a counter is incremented each time the error rate is unacceptable and decremented not to exceed zero whenever the error rate is acceptable If the counter continually increments such that it reaches the predictive threshold a predictive failure is signaled This counter is referred to as the Failure History Counter There is a separate Failure History Counter for each attribute SEAGATE ENTERPRISE CAPACITY 3 5 HDD v4 SAS PRODUCT MANUAL REV 15 5 2 4 Thermal monitor Enterprise Capacity 3 5 HDD v4 drives implement a temperature warning system which 1 Signals the host if the temperature exceeds a value which would threaten the drive

PRODUCT MANUAL REV 11 3 2 Mode Sense data The Mode Sense command provides a way for the drive to report its operating parameters to the initiator The drive maintains four sets of mode parameters 1 Default values Default values are hard coded in the drive firmware stored in flash E PROM nonvolatile memory on the drive s PCB These default values can be changed only by downloading a complete set of new firmware into the flash E PROM An initiator can request and receive from the drive a list of default values and use those in a Mode Select command to set up new current and saved values where the values are changeable Saved values Saved values are stored on the drive s media using a Mode Select command Only parameter values that are allowed to be changed can be changed by this method Parameters in the saved values list that are not changeable by the Mode Select command get their values from default values storage When power is applied to the drive it takes saved values from the media and stores them as current values in volatile memory It is not possible to change the current values or the saved values with a Mode Select command before the drive achieves operating speed and is ready An attempt to do so results in a Check Condition status On drives requiring unique saved values the required unique saved values are stored into the saved values storage location on the media prior to shipping the drive Som
