Figure 122. Security Erase Unit Command (F4h)
The Security Erase Unit command initializes all user data sectors and then disables the device lock
function.
Note that the Security Erase Unit command initializes from LBA 0 to Native MAX LBA. The Host MAX LBA
set by the Initialize Drive Parameter or the Set MAX Address command is ignored. So the protected area
by the Set MAX Address command is also initialized.
This command requests the transfer of a single sector data from the host including the information
specified in the figure below.
If the password does not match, the device rejects the command with an Aborted error.
