The PREVENT/ALLOW MEDIUM REMOVAL command allows or inhibits
media ejection on the device.
A value of 0 in the Prevent bit allows ejection and a value of 1 disables ejection.
The power-on default value is Enabled.
If there is any data not written yet in the write cache, the ODD completes writing
on media, then allows ejection.
Hard reset resets the prevent state to allow ejection.
