(32) SECURITY ERASE UNIT (F4h)
This command erases all user data. This command also invalidates the user
password and releases the lock function.
The host transfers the 512-byte data shown in Table 5.10 to the device. The
device compares the user password or master password in the transferred data with
the user password or master password already set. The device erases user data,
invalidates the user password, and releases the lock function if the passwords are
the same.
Although this command invalidates the user password, the master password is
retained. To recover the master password, issue the SECURITY SET
PASSWORD command and reset the user password.
If the SECURITY ERASE PREPARE command is not issued immediately before
this command is issued, the Aborted Command error is returned.
Issuing this command while in FROZEN MODE returns the Aborted Command
error.
