    11.5.2 LBA addressing mode Logical sectors on the device shall be linearly mapped with the first LBA addressed sector (sector 0) being the same sector as the first logical CHS addressed sector ( cylinder 0, head 0, sector 1). Irrespective of the logical CHS translation mode currently in effect, the LBA address of a given logical sector does not change.

  • Page 93: 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. The drive implements the following set of functions: 1.

  • Page 94: 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 automa- tically enters the standby mode.

  • Page 95: Advanced Power Management (Able-3) Feature

    11.7 Advanced Power Management (ABLE-3) feature This feature provides power saving without performance degradation. The Adaptive Battery Life Extender 3 (ABLE-3) technology intelligently manages transition among power modes within the device by monitoring access patterns of the host. This technology has three idle modes; Performance Idle mode, Active Idle mode, and Low Power Idle mode.

The algorithm calculates the expected average saving energy and response delay for next command in several transition time case based on this assumption. And it selects the most effective transition time with the condition that the calculated response delay is shorter than the value calculated from the specified level by Set Feature Enable Advanced Power Management command.

    11.8 S.M.A.R.T. Function The intent of Self-monitoring, analysis, and reporting technology (S.M.A.R.T.) is to protect user data and prevent unscheduled system downtime that may be caused by predictable degradation and/or fault of the device. By monitoring and storing critical performance and calibration parameters, S.M.A.R.T. devices employ sophisticated data analysis algorithms to predict the likelihood of near-term degradation or fault condition.

    11.8.6 S.M.A.R.T. operation with power management modes The device saves attribute values automatically on every head unload timing except the emergency un- load, even if the attribute auto save feature is not enabled. The head unload is done not only by Standby, Standby Immediate, or Sleep command or Hard Reset, but also by the automatic power saving functions like ABLE-3 or Standby timer.

  • Page 105: Protected Area Function

    11.10 Protected Area Function Protected Area Function is to provide 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.

  • Page 106: Set Max Security Extension Commands

    Write information data such as BIOS code within the protected area. Change maximum LBA using Set Max ADDRESS command to 0FBFFFh with nonvolatile option. From this point, the protected area cannot be accessed until next Set Max ADDRESS command is issued.

  • Page 107: Figure 69. Set Max Security Mode Transition

    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.

    11.11 Address Offset Feature (vendor specific) Computer systems perform initial code loading (booting) by reading from a predefined address on a disk drive. To allow an alternate bootable operating system to exist in a reserved area on a disk drive this feature provides a Set Features function to temporarily offset the drive address space.

  • Page 110: 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.

  • Page 111: Write Cache Function

    11.13 Write Cache function Write cache is a performance enhancement whereby the device reports completion of the write command (Write Sectors and Write Multiple) to the host as soon as the device has received all of the data in its buffer.

    11.15 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.

    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 115 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.

Upon receipt of the S.M.A.R.T. Read Attribute Values subcommand from the host, the device asserts BSY, saves any updated Attribute Values to the Attribute Data sectors, asserts DRQ, clears BSY, asserts INTRQ, and then waits for the host to transfer the 512 bytes of Attribute Value information from the device via the Data Register.

    13.32.1.5 S.M.A.R.T. Execute Off-line Immediate (subcommand D4h) This subcommand causes the device to immediately initiate the set of activities that collect Attribute data in an off-line mode (off-line routine) or execute a self-test routine in either captive or off-line mode. The Sector Number register shall be set to specify the operation to be executed.

Enable Operations subcommand, Attribute Values are neither monitored nor saved by the device. The state of S.M.A.R.T.—either enabled or disabled—will be preserved by the device across power cycles.
