cleared by Subcommand 89h Disable Address Offset Mode, Hardware reset or Power on Reset. If Reverting to 
Power on Defaults has been enabled by Set Features command, it is cleared by Soft reset as well. Upon entering 
offset mode the capacity of the drive returned in the Identify Device data is the size of the former protected area. A 
subsequent Set Max Address command with the address returned by the Read Max Address command allows access 
to the entire drive. Addresses wrap so the entire drive remains addressable.

If a nonvolatile protected area has not been established before the device receives a Set Features Enable Address 
Offset Mode command, the command fails with Abort error status.

Disable Address Offset Feature removes the address offset and sets the size of the drive reported by the Identify 
Device command back to the size specified in the last nonvolatile Set Max Address command.

Identify Device data, word 83, bit 7 indicates the device supports the Address Offset Feature. Identify Device data, 
word 86, bit 7 indicates the device is in Address Offset mode.

Any commands which access sectors across the original native maximum LBA are rejected with error, even if the 
access protection is removed by a Set Max Address command.

Read Look Ahead operation is not carried out, even if it is enabled by the Set Feature command.
