Seagate ST318418N Inquiry Vital Product data, Unit serial number page 80h, Data code page C1h

50 Barracuda 36ES2 Product Manual, Rev. B

9.3.1Inquiry Vital Product data

Instead of the standard Inquiry data shown in Table 6, the initiator can request several Vital Product Data pages by setting the Inquiry command EVPD bit to one. The SCSI Interface Product Manual, part number 75789509, 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.

Table 7 shows the Vital Product Data pages for the drives of this product manual. “Y” means reporting that par- ticular parameter is supported, but it may be different for each drive.
