Figure 66. Set Max Security Mode Transition - IBM DJSA-210 - Travelstar 10 GB Hard Drive Specifications

This command requests a transfer of a single sector of data from the host. The figure shown above
defines the content of this sector of information. The password supplied in the sector of data transferred is
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 is 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 returns command aborted until a power cycle.
The Set Max FREEZE LOCK command allows the host to disable the SET MAX commands (including Set
Max UNLOCK) until the next power cycle. When this command is accepted the device is in the Set Max
Frozen mode.
The Set Max password, the Set Max security mode and the unlock counter don't persist over a power
cycle but persist over a hardware or software reset.
NOTE: If this command is immediately preceded by a Read Native MAX ADDRESS command regardless
of Feature register value, it shall be interpreted as a Set Max ADDRESS command.
