03 means SCSI-3 (Ultra160) implemented.
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 informa-
tion is also given in the Vital Product Data page C0h, together with servo RAM and ROM release num-
bers.
S# Eight ASCII digits representing the eight digits of the product serial number.

10.3.1 Inquiry Vital Product data
Instead of the standard Inquiry data shown in Table 9, the initiator can request several Vital Product Data
pages by setting the Inquiry command EVPD bit to one. The SCSI Commands 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.
