Figure 69. Set Max Security Mode Transition - IBM IC25N040ATCS04 - Travelstar 40 GB Hard Drive Specifications

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 password, the Set Max security mode, and the unlock counter do not 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, it shall be
interpreted as a Set Max ADDRESS command regardless of Feature register value.
