Returned data:
INQUIRY returns its standard data if the EVPD bit is zero, or returns a page of data as specified by the Page Code field when EVPD is one.
Standard Inquiry Data format (LUN0)
This is the data returned by the drive in response to an Inquiry command with its EVPD bit set to zero. The data also depends on the value of the LUN field in the Inquiry CDB, the LUN value in the identify message and the configuration of the drive.
