Figure 96. 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
is set by the Initialize Drive Parameter or the Set MAX ADDRESS command is ignored. The protected
area by the Set MAX ADDRESS command is also initialized.
This command requests the transfer of a single sector of data from the host including information specified
in Figure 96.
If the password does not match then the device rejects the command with an Aborted error.
