Table 14 lists the Standard Inquiry command data that the drive should return to the initiator per the format given in the SCSI Interface Product Manual, part number 75789509, Inquiry command section.

Note. Seagate has chosen to set this bit to 03, SCSI-3 (Ultra160) implemented, rather than 04, SCSI-4 (Ultra320) implemented, due to compatibility issues with some host bus adapters. This setting will not affect the Ultra320 functionality of the drive. [ ]2 The drive can be changed between these two configurations: 02 means response data in SCSI-2/SCSI-3 format. 12 means the drive uses the hierarchical addressing mode to assign LUNs to logical units (default is 12). R# Four ASCII digits representing the last four digits of the product Firmware Release number. This information is also given in the Vital Product Data page C0h, together with servo RAM and ROM release numbers. S# Eight ASCII digits representing the eight digits of the product serial number. [ ]3 Bytes 18 through 26 reflect model of drive. The table above shows the hex values for Model ST973401LC. Refer to the values below for the values of bytes 18 through 26 of you particular model: ST973401LC ST936701LC 39 37 33 34 30 31 4C 43 20 39 33 36 37 30 31 4C 43 20 [ ]4 Copyright Year - changes with actual year. 9.3.1 Inquiry Vital Product data Instead of the standard Inquiry data shown in Table 14, the initiator can request several Vital Product Data pages by setting the Inquiry command EVPD bit to one. The SCSI Command Reference Manual lists the Vital Product Data pages and describes their formats. A separate Inquiry command must be sent to the drive for each Vital Product Data page the initiator wants the drive to send back. 9.3.2 Mode Sense data The Mode Sense command provides a means for the drive to report its operating parameters to the initiator. The drive maintains four sets of Mode parameters, Default values, Saved values, Current values and Changeable values. Default values are hard coded in the drive firmware that is stored in flash EPROM nonvolatile memory on the drive PCBA. Default values can be changed only by downloading a complete set of new firmware into the flash EPROM. 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.
