INTERFACE COMMANDS

Read Native Max Address

This command returns the native maximum address. The native maximum address is the highest address accepted by the drive in the factory default condition. The native maximum address is the maximum address that is valid when using the SET MAX ADDRESS command.

Set Max

Individual SET MAX commands are identified by the value placed in the Features register. After successful command completion, all read and write access attempts to addresses greater than specified by the successful SET MAX ADDRESS command are rejected with an IDNF error. IDENTIFY DEVICE response words 1, 54, 57, 60 and 71 will reflect the maximum address set with this command.

Set Max Password

This sub-command requests a transfer of a single sector of data from the host. The password is retained by the drive until the next power cycle.

Set Max Lock

After this sub-command is completed any other SET MAX commands except SET MAX UNLOCK and SET MAX FREEZE LOCK are rejected. The drive remains in this state until a power cycle or the acceptance of a SET MAX UNLOCK or SET MAX FREEZE LOCK command.

Set Max Unlock

This sub-command requests a transfer of a single sector of data from the host. The password supplied in the sector of data transferred will be compared with the stored SET MAX password.

If the password compare fails, then the drive 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 will be decremented for each password mismatch when SET MAX UNLOCK is issued and the drive is locked. When this counter reaches zero, then the SET MAX UNLOCK command will return command aborted until a power cycle.

If the password compare matches, then the drive will make a transition to the Set_Max_Unlocked state and all SET MAX commands will be accepted.

Set Max Freeze Lock

After sub-command completion any subsequent SET MAX commands are rejected. Commands disabled by SET MAX FREEZE LOCK are:
