You may then turn off the drive in the following order: 1. Issue Standby Immediate or sleep command 2. Wait until COMMAND COMPLETE STATUS is returned. (It may take up to 350 ms in a typical case.) 3. Terminate power to drive This power-down sequence should be followed for entry into any system power-down state, system suspend state, or system hibernation state.
Page 88: Power Management Features
11.6 Power management features The power management feature set permits a host to modify the behavior in a manner which reduces the power required to operate. The power management feature set provides a set of commands and a timer that enables a device to implement low power consumption modes.
Page 89: Standby Timer
11.6.4 Standby timer The standby timer provides a method for the device to automatically enter standby mode from either active or idle mode following a host programmed period of inactivity. If the device is in the active or idle mode, the device waits for the specified time period and if no command is received, the device automatically enters the standby mode.
Page 90: Performance Idle Mode
• A SET FEATURES subcommand to enable Advanced Power Management • A SET FEATURES subcommand to disable Advanced Power Management The Advanced Power Management feature is independent of the Standby timer setting. If both Advanced Power Management level and the Standby timer are set, the device will go to the Standby state when the timer times out or the device's Advanced Power Management algorithm indicates that it is time to enter the Standby state.

system of a negative reliability status condition, the host system can warn the user of the impending risk of a data loss and advise the user of appropriate action. Since S.M.A.R.T. utilizes the internal device microprocessor and other device resources, there may be some small overhead associated with its operation.

If the attribute auto save feature is enabled, attribute values will be saved after 30 minutes have passed since the last saving, besides above condition. 11.9 Security Mode Feature Set Security Mode Feature Set is a powerful security feature.
Page 93: Master Password Revision Code
The system manufacturer or dealer who intends to enable the device lock function for end users must set the master password even if only single level password protection is required. Otherwise, the default master password which is set by Hitachi Global Storage Technologies can unlock a device that is locked with a user password 11.9.4 Master Password Revision Code This Master Password Revision Code is set by Security Set Password command with the master password.

11.9.4.4 User Password lost If the User Password is forgotten and High level security is set, the system user cannot access any data. However the device can be unlocked using the Master Password. If a system user forgets the User Password and Maximum security level is set, data access is impossible. However the device can be unlocked using the Security Erase Unit command to unlock the device and erase all user data with the Master Password.

Page 97: Protected Area Function
11.10 Protected Area Function Protected Area Function provides a protected area which cannot be accessed via conventional methods. This protected area is used to contain critical system data such as BIOS or system management information. The contents of the entire system main memory may also be dumped into the protected area to resume after a system power off. The LBA/CYL changed by the following commands affects the Identify Device Information.
Page 98: Set Max Security Extension Commands
From this point the protected area cannot be accessed until the next Set Max ADDRESS command is issued. Any BIOS, device driver, or application software accesses the drive as if it is a 528 MB device because the device behaves like a 528 MB device. 3.
Page 99: Address Offset Feature (Vendor Specific)
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.
Page 100: Identify Device Data
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 58: Device address map before and after Set Feature 11.11.2 Identify Device Data Identify Device data, word 83, bit 7 indicates the device supports the Address Offset Feature.
Page 101: Seek Overlap
11.12 Seek Overlap The drive provides accurate seek time measurement method. The seek command is usually used to measure the device seek time by accumulating execution time for a number of seek commands. With typical implementation of the seek command, this measurement must include the device and host command overhead. To eliminate this overhead, the drive overlaps the seek command as described below.
Page 102: Reassign Function
11.14 Reassign Function The Reassign Function is used with read commands and write commands. The sectors of data for reassignment are prepared as the spare data sector. The one entry can register 256 consecutive sectors maximum. This reassignment information is registered internally, and the information is available right after completing the reassign function.

11.15 48-bit Address Feature Set The 48-bit Address feature set allows devices with capacities up to 281,474,976,710,655 sectors. This allows device capacity up to 144,115,188,075,855,360 bytes. In addition, the number of sectors that may be transferred by a single command are increased by increasing the allowable sector count to 16 bits.

12.0 Command protocol The commands are grouped into different classes according to the protocols followed for command execution. The command classes with their associated protocols are defined below. For all commands, the host must first check to see if BSY = 1, and should proceed no further unless and until BSY = 0.
Page 106: Data Out Commands
f. The device sets DRQ = 0 after the sector (or block) has been transferred to the host. 4. For the Read Long command: a. The device sets BSY = 1 and prepares for data transfer. b. When the sector of data is available for transfer to the host, the device sets BSY = 0 and DRQ=1 and interrupts the host.
