Travelstar 5K100 Hard Disk Drive Specification

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.

Table 55: Device address map before and after Set Feature

11.12.2

Identify Device Data

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.

11.12.3

Exceptions 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 and Write Cache Function are not carried out in Address Offset mode, even if they are

enabled by the Set Feature command.
