This command is not immediately preceded by a READ NATIVE MAX ADDRESS command. If this command is 
immediately preceded by a READ NATIVE MAX ADDRESS command, it shall be interpreted as a SET MAX 
ADDRESS command. 
This command requests a transfer of a single sector of data from the hostTable 10.8-7 defines the content of this 
sector of information.   
The password supplied in the sector of data transferred shall be compared with the stored SET MAX password. 
If the password compare fails, then the device returns command aborted and decrements the unlock counter. 
On the acceptance of the SET MAX LOCK command, this counter is set to a value of five and shall be 
decremented for each password mismatch when SET MAX UNLOCK is issued and the device is locked. When 
this counter reaches zero, then the SET MAX UNLOCK command shall return command aborted until a power 
cycle. 
If the password compare matches, then the device shall make a transition to the Set_Max_Unlocked state and 
all SET MAX commands shall be accepted.
