From: Ronnie Sahlberg <ronniesahlb...@gmail.com>
The START STOP UNIT command will only eject/load media if
power condition is zero.
If power condition is !0 then LOEJ and START will be ignored.
>From MMC (sbc contains similar wordings too)
The Power Conditions field requests the block device to be placed
in the power condition defined in
Table 558. If this field has a value other than 0h then the Start
and LoEj bits shall be ignored.
