(36) SECURITY DISABLE PASSWORD (X’F6’)
This command invalidates the user password already set and releases the lock
function.
The host transfers the 512-byte data shown in Table 5.28 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.
Issuing this command while in LOCKED MODE or FROZEN MODE returns the
Aborted Command error.
(The section about the SECURITY FREEZE LOCK command describes LOCKED
MODE and FROZEN MODE.)
