The MODE SENSE command provides a means for a Device to report parameters. It is a complementary
command to the MODE SELECT command.
A Disable Block Descriptors (DBD) bit of zero indicates that the Device shall return one block descriptor in the
returned MODE SENSE data. A DBD bit of one specifies that the Device shall not return any block descriptors in
the returned MODE SENSE data.
The Page Code specifies which page or pages to return.
If a MODE SENSE command is attempted with a page code value not implemented, the Device shall return
"Check Condition" status and shall set the Sense Key to ILLEGAL REQUEST and the Additional Sense Code to
INVALID FIELD IN CDB.
A page code of 3Fh indicates that all pages implemented by the Device shall be returned. Page 00h, if
implemented, shall be returned after all other pages. Devices that implement more than 255 bytes of mode page
parameter data and block descriptors shall return "Check Condition" status to a MODE SENSE request of 3Fh in
the page code field. The Sense Key shall be set to ILLEGAL REQUEST and the Additional Sense Code shall be
set to INVALID FIELD IN CDB.
The Drive returns the current parameter values for the specified page code. The current values returned are:
1. The parameters set in the last successful MODE SELECT command.
2. The default values if a MODE SELECT command has not been executed since the last power-on, hard
RESET condition, or Device reset, or not ready to ready transition.
