(30) SECURITY DISABLE PASSWORD (F6h)
This command invalidates the user password already set and releases the lock
function.
The host transfers the 512-byte data shown in Table 5.13 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, 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 user password or master password transferred from the host does not match,
the Aborted Command error is returned.
