The security features of Self Encrypting Drive models are based on the TCG Storage Architecture Core Spec ification and the TCG Storage Workgroup Security Subsystem Class Enterprise_A specification with addi tional vendor unique features as noted in this product manual 3 1 1 Electromagnetic compatibility The drive as delivered is designed for system integration and installation into a suitable enclosure prior to use The drive is supplied as a subassembly and is not subject to Subpart B of Part 15 of the FCC Rules and Regulations nor the Radio Interference Regulations of the Canadian Department of Communications The design characteristics of the drive serve to minimize radiation when installed in an enclosure that provides reasonable shielding The drive is capable of meeting the Class B limits of the FCC Rules and Regulations of the Canadian Department of Communications when properly packaged however it is the user s responsibility to assure that the drive meets the appropriate EMI requirements in their system Shielded I O cables may be required if the enclosure does not provide adequate shielding If the I O cables are external to the enclosure shielded cables should be used with the shields grounded to the enclosure and to the host controller 3 1 1 1 Electromagnetic susceptibility As a component assembly the drive is not required to meet any susceptibility performance requirements It is the responsibility of those
7. Extended test Function Code 010b The objective of the extended test option is to empirically test critical drive components For example the seek tests and on track operations test the positioning mechanism The read operation tests the read head element and the media surface The write element is tested through read write read operations The integrity of the media is checked through a read verify scan of the media Motor functionality is tested by default as a part of these tests The anticipated length of the Extended test is reported through the Control Mode page 6 2 6 2 4 Log page entries When the drive begins DST it creates a new entry in the Self test Results Log page The new entry is created by inserting a new self test parameter block at the beginning of the self test results log parameter section of the log page Existing data will be moved to make room for the new parameter block The drive reports 20 param eter blocks in the log page If there are more than 20 parameter blocks the least recent parameter block will be deleted The new parameter block will be initialized as follows 1 The Function Code field is set to the same value as sent in the DST command 2 The Self Test Results Value field is set to Fh 3 The drive will store the log page to non volatile memory After a self test is complete or has been aborted the drive updates the Self Test Results Value field in its Self Test Results Log page in non volatile mem
