This command transfers the information showing the HDD's characteristics
(INQUIRY data) to the application client.
This command is executed normally even in cases where the UNIT ATTENTION
condition is held, and the UNIT ATTENTION condition is not cleared. This
command is also executed normally when the disk drive is not in the ready state.
A CHECK CONDITION status is reported for this command and it is terminated
abnormally only in the case that one of the following conditions is detected.
• There is an error in the specifications of the CDB.
• It is impossible to send INQUIRY data because of an HDD hardware error.
• Applicability to overlapping command exception conditions (See Section
2.8.1.)
If both the "EVPD" and "CmdDt" bits are one, this command is terminated by a
CHECK CONDITION status (ILLEGAL REQUEST [=5] / Invalid Field in CDB
[=24-00]).
