Table 140 Security Disable Password Command (F6h)
The Security Disable Password command disables the security mode feature (device lock function).
The Security Disable Password command requests a transfer of a single sector of data from the host including
information specified in Table 139 . Then the device checks the transferred password. If the User Password or
Master Password matches the given password, the device disables the security mode feature (device lock
function). This command does not change the Master Password which may be re-activated later by setting User
Password. This command should be executed in device unlock mode.
