Set Max Unlock (Feature = 03h)
Table 144: Set Max Unlock command (F9h)
If this command is immediately preceded by a Read Native Max Address command, the device regards it as Set
Max Address command
This command requests a transfer of a single sector of data from the host including the information specified in
Table 141: “Set Max Set Password command” on page 191 with the stored SET MAX password.
If the password compare fails, the device returns an abort error to the host and decrements the unlock attempt
counter. This counter is initially set to 5 and is decremented for each password mismatch. When this counter
reaches zero, all Set Max Unlock commands are rejected until a hard reset or a power off occurs.
If the password compare matches, the device sets the Set_Max_Unlocked state and all Set Max commands are
accepted.
